Sansui G-7700....... pictures? info? anything? please?

[Night Wolf]

gello all, my first new thread in the Sansui room, I thought I would never be in here as I bevcer owned a Sansui.....

well, to make a long story short, I got a Sansui G-7700 for free, just have to pay shipping, at another forum I go to, a guy named Rob (cool guy) said he was throwing away a Sansui G-7700, G-3000 and a Onkyo TX-3000, so I imeditly e-mailed him (actualy I have talked to him before) and asked him if he would send them to me if I pay shipping, he said the only unit worth saving is the G-7700 (the other 2 have bad right channels, and he said they were very low end units) anyway, he said the G-7700 has intermint problems, don't know exactly what is wrong, he said it is in excelent cosmetic conditon.

does anyone have any pictures? I don't even know what this look like except for the little picture on the review Ckelly posted (did a search) yes, I "bought" it without knowing anything about it, but I trust Rob. anyway while also searching I found out it is 120wpc (no pre-out/power-in :( ) and was $800 new, wow

so any info, pictures, anything will be great, shipping and all that will proably be around $50, so do you think I got a good deal? I first plan to open it up, and see what it has, then try and fix it, maybe you guys could help me on that, but least of all, I can just say I own a nice vintage Sansui, and have it fo display, but I am going to really try and fix it (whatever the problem is, I'll have to test it all out when I get it)

Thanks guys (in advance :) )

[Night Wolf]

hmm, I am doing a search on this now, I noticed this is a DC amp? can someone please tell me what a DC amp is and what the differnce is?

I found this picture of the inside, it looks rather bare, and the caps are kinda small, but in the review they said it was pushing 170wpc into 8 ohms when clipped, any help though is great

Hello NW:

All you have to do is go to www.sansui.us and click on Receivers from the Homepage there. Select G-9700- thats the top Line model at 200 W (Member 'Bully' here has one that he is very fond of). The G-7700 is 120W and looks almost identical minus a few minor features. I have a G-7700 and its great receiver. Very powerful. Another member here, Thor, also has one or had one- it was supposedly underpowered for his CV spkrs- dunno why that would be the case other than the extreme levels he prefers to listen to but you'd have to ask him about that.

The review is from July 80 Stereo Review magazine which I have- if you can make out the print, that review should tell you most of what you need to know. If you need more info than that, I do have brochure, manuals etc. for it.

There were 3 generations of G Series models between 1978 to 1980. The G-9700...4700 Line is the 3rd and last - characterized by led power meters, green Safely Operate led, and analog tuning dial with digitally quartzed lock tuning/digital station readout- as on TU-719 Tuner. You can check the Sansui listings on Ebay and from that you will quickly become acquainted with alot of the models they made- also the Completed Auctions section.

As it says on the front panel- PURE POWER. I think you will be very impressed by it when you get it.

Regards, B/F.

[BeatleFred]

DC refers to Direct Coupled- no capacitors in the signal path for the purest signal.

[Night Wolf]

hmmm, you mentioned about the manuals, you have a user manual and service manual? if so, would you make a copy and I could buy them from you? or maybe a trade or something?

if you could send anything you have about it, that would be great, do you need my e-mail address? InoventionsEast@optonline.net, if you need anything else, let me know.

DC refers to Direct Coupled- no capacitors in the signal path for the purest signal.

ok, I am confused, what do they mean? would that explain the, errrr, "lack of" guts it has (in that picture? or am I completly missing something

so, it sounds good? is it real power ful also? would it compare to my Kenwood KR-8010?

Thanks

[THOR]

Yes I had one and yes it is a fabulous receiver, I have since passed it on to Big Mac.

And yes it was not up to the task of powering my CV's, it could do it but barely and it didn't like it much, thing got so hot you could fry bacon on it. But my CV's also recommend 500 watts continous ;)

[BeatleFred]

NW:

I have a WHOLE COLLECTION of Sansui literature. And stacks upon stacks of hi fi mags. In fact, I have been spending the last couple of hours trying to reorganize it again. Everytime I organize it, it goes back to being jumbled again because I keep referring back to it to look up information. Just like washing dishes- the sink is clean, and then all it takes is for Ya to eat and drink a few things and before you know it the whole sink is a mess.

Yes, I can make a xerox of the G-7700 stuff for you if you can compensate the copy/postage cost. I have a few other copies to make for some people so I will try and do that all in one shot this week and that way, dont have to run back and forth each day to the Post Office to mail out. You can email me with your address and I'll let you know in the next day or two what cost would be.

The G-7700 is extremely powerful- the July 80 issue says so in regards to all the testing they subjected it to. (Though THOR wasnt there at the time:) Powerful, meaning it can do well into low-Z spkr loads- down to even approx 2 ohms. You didnt mention what spkrs you have, but I would think the G-7700 would be more than sufficient for them.


As I said beforee DC refers to eliminating caps in the signal path. Some Sansui integrated amps offer the option via a switch to select dc or ac coupled. DC for theoretically the purest sound, ac for protection in that it utilizes blocking capacitance to protect DC from reaching the speakers.

I will be around during the week to answer more questions if you have them, but for now I have some other things to tend to. In the meantime, there is no need to be overly concerned about the size of the caps and whatnot inside, it is VERY POWERFUL I assure you.

B/F.

[Night Wolf]

BF, could you send me your e-mail address?

BTW I have customly modified (by me) JBL L100's

wow, you seem to have alot of stuff AFA all the old mags and all

would you be able to let me know if you have any of the floowing:

Kenwood KR-8010
Kenwood KA-1500
Sony TA-2650
Sony ST-3950

if you have ANYTHING thing on these, that would be great (although I have a service manual for the 8010)

sure I'll pay the copy and postage and all that, just either give me your e-mail address or send me a e-mail @ InoventionsEast@optonline.net

wow, thanks I really appreciate it.

Thor,, we all know spekaer ratings on speakers are useless :)

anyway, Thor, wouldn't that be real cool if someday we got my L100's vs. your CV, and see which is the better spekaer? although you have that exta 15" woofer on the bottom, I don't know if woujld be close (I made my L100's bi-amp) although I would have to put my money on my L100's :D

[THOR]

You would lose your money, these are not normal CV's they sold for $1000 a piece in 91', I had a pair of Pioneer HPM 100's which are very similar to the JBL's I actually think they were designed by the same guy, I let them go for what I paid for and felt no pain since they could not compete with the CV's ;)

my L100's were $1,000 new in '78

those Pioneers are NOTHING like the L100's the L100 is a spekaer in it's own

unless of course, it used a L100 cab. 123A-3 woofer, LE5-2 midrange (said to be JBL's best midrange ever made) and LE25 tweeter :D

but Thor, which ever the case was, that would be loads of fun. then after that we could have a huge party, yeah stack my L100's ontop of your CV, and then just run all the power we could to everything :D

hey I can dream can't I :D

[THOR]

The HPM 100 and L100 are very similar ask Bully.

$1000 a piece that means mine were $2000 for the pair ;)

No way you are stacking those nasty ass broken tweeter screwdriver damaged mid driver things on my beautiful, pristine, all original and fully functional speakers :D

yes, but $1,000 back in '78 is equal to $3,200 or so in todays money :D

nasty? HA! my L100's are completly restored (by me) best looking L100's in the country, shiny too, with 5 coats of super-high gloss polyeurthane (along with everything else I did)

your right they, don't don't belong ontop of CV, they belong on solid gold pedistals customized for the L100 :D

[THOR]

You call blowing a tweeter and poking a screwdriver thru the mid restoration? :confused: :D

[Night Wolf]

Originally posted by THOR

ok, so there was alittle detor (actualy I already restored them before this happend)

and I didn't really blow the tweeter from cranking the music and clipping my amps (which is almost impossible) but more like have negitive from one amp tough positive of the other, and the spekaer being hooked up to the same amps, thus sending a major power surge to the spekaer, but whos keeping track ;)

[Night Wolf]

ok, getting back on subject, Rob saud that when playing in FM, the right channel goes out and very weak, but when you switch it to mono, both channels work

he also said that when he hooked a cdp into aux that after 5min or so, the right channel would cut out, then come back in, and keep doing that

besides that, he said it works great, and is in great cosmetic condition

so, anyone know what it could be? easy fix? and most of all, is it worth my $50-$60 or so for it to be shipped?

too bad it didn't have pe-out/power-in, maybe I couild add that myself, becuase is the preamp is bad, I would be happy with just using it as a power amp, and also, it's huge and would be the only Sansui I own, so I would be able to say I own a big G series Sansui rec. :D

but anyway, so do you think I should go for it? and what could the problem be?

[THOR]

If you are getting it for free it should only cost about $40 to get it shipped I shipped mine from Maine to Michigan to Biggie Mac for about that. It is a superb reciever, if it had had pre outs I woulda kept it and used it as my preamp/tuner, the knobs are just awesome. That big fat volume knob is da bomb.

[Night Wolf]

here's the thing, it will only cost $20 to be shipped, but Rob said he dosn't want to bother packing it, so he brought it to Mailboxes etc.... and have them ship it and everything, it was $80! they were going to doubal box it and all, and I am like woha, that is kinda high, I could probaly save $10 by getting it single boxed, but still that is not that good

I dunno, Rob said it dosn't want to bother with it anymore, maybe I'll just ask him if it is ok that I send a $50 MO (since it shouldn't be anymore then $25 or so to ship) and for him to just keep whatever is left over, just thanking him for his time and effort

but I am asking, is it worth it? are those problems pretty easy to fix or not? what is the point of the digital tuner, if it is already analog? and like I said before, is it really worth it, or should I just save my money? I am in kinda of a rush to get answers though, becasue mailboxes etc... never called back (like they said) and I'll e-mail Rob latter telling him what I figured out

if I don't buy it, it is going in the trash, and I just can't see such a fine Sansui get thrown away, but then after shipping and then cost to repaire it (although I would tinker around withit myself) it might not be worth it

I really have no use for it, as I have my dual KR-8010's running in bi-amp to my L100's, I mainly wanted it, becuase I could say I own a big vintage Sansui, I can't see something like that just get thrown away, and I could tinker around with it, which is kinda what I want to do, and if all else fails, just keep it on display with my other vintage gear for all to see.

but I am completly lost here, I mean, $50 I would do it, that is like the limit, $80 is too much, but then if it is like $60, that is more then I wanted to spend, but I tell myself, well it's only $10 more

he said it is in great cosmetic condition, and like I said, maybe it will give me something to mess around with. becuase after reading the 1980 Stereo Review, it seems like a real nice unit, but honestly, I was expecting a big riodial transformer and 4 big caps, not a normal power supply and 2 caps, I mean, honestly, after looking at my KR-8010, which I thought was "weak" AFA internal guts, it makes that G-7700 *link is posted above) look even smaller, although I know that has nothing to do with how the rec. sounds or performs, I figured, if it didn't work, atleast I could have something o show off :D


ahhh please help everyone (and quikcly) I really need to know if I should go for it or not, and if the problems are an easy fix or not, I mean if it worked great, then I would take it, no question (but then again Rob wouldn't be throwing it away if it worked great) so maybe I can get help. maybe it is the output transistors? don't know, seems like 4/5 vintage Sansui have minor or major problems, I mean I always hear about them with problems, and even a friend with AU-517 with problems, funny though becuase all my Kenwood and Sony gear do not have 1 problem at all, and I would consider Sansui a bit higer then Kenwood and Sony

but please, I need help and guidence on this one, I dunno what to do :dunno:

[Night Wolf]

so is this thing worth $65-$70 total for the condition it is in?!?!?!?!?

sorry to keep asking about it, but I have no idea as I never had any Sansui gear, and I really need to know soon

[BeatleFred]

Hello NW:

Any info I have on Kenwood's & Sony would be located in the stacks upon stacks of hi fi mag backissues I have. It would be tough right now to find the time to search through it all for the info you want on those specific models. There's a site that does exist on which someone has posted many years worth of Stereo Review, Hi Fidelity, and Audio backissues and which models were reviewed in which issue- that site is moving to a new address and will be Up in the next few days. Useful for me to use as a guideline to help organize all my stuff which I am currently in the process of doing (And would be able to make more progress with if only I could ever tear myself away from this computer which I seem to be on for hours straight when I get home from work- can never seem to get caught up). When that Site is Up, I can let you know and if you see a specific issue that has any model you are interested in, it would be alot easier for me then to get the info from the mag-as I can then go right to the specific year/month. It will be enough Work for me to go thru all my mags just to index all the Sansui ads, reviews, etc... trying to do it for other brands as well would really be a daunting task. But I just might give it a try:)

As for G-7700: If you do buy it and need the manuals, I have them and making copies shouldnt be a prob. From what you mentioned: the problems it has could be a # of things- loose connections, dirty switch or some components that need replacing. Could be a simple fix or could be more complicated.
(As for the tuner section- that was the technology circa 1980 as things were transitioning from analog to digital- alot of other receivers' tuner sections had the same analog dial with digital readout- including Tuners itself such as the Sansui TU-719 which I have). Its really your call if you want to buy it or not and what max price is you want to pay. If the Seller is just gonna chuck it in the garbage, I dont see why he would be overly demanding to try and squeeze as much $$ outve you as possible. If tinkering is what you like to do, then it sounds like this unit will provide that for you. If you feel you need more asurance that it will work reliably, you can pass on it w/o worrying too much- as at some point there will be other G-7700's that come along on Ebay or other G models for that matter, so its not like you are missing a big chance to ever own one, they'll be around. Or you can consider maybe spending more and getting one that is 100% cond also. Then again, 50, 60 bucks isnt too unreasonable- If need be that its gets split into Parts, its value in Parts might exceed what its value is as a whole which might justify its purchase. Basically you can look at it from several viewpts- your call though which option you think is best for you. B/F.

[BeatleFred]

As for THOR and the CV's/G-7700, if THOR can provide some info on the speakers- such as their efficiency, perhaps an explanation can be obtained for why the G-7700 seemed to be struggling with his speakers as he claimed. Has Thor been told by other owners of his model (and also- what is the model name or #of those spkrs?) or by CV themself that these speakers are notoriusly rough on thea majority of amps/receivers out there and that huge power (current) is absolutely essential for the spks? I'd be curious to know more about this.

[THOR]

Ask and you shall recieve:

Here are the specs:

http://audiokarma.org/forums/showthread.php?s=&threadid=124&highlight=story+and+pics

And they are just about right because I am currently running just the 15" woofers in the bottom each with their own amp, each amp provides 300 wpc, I cranked the music so loud this weekend that I tripped their protection relays, and you wonder why a 120wpc reciever had problems?

BTW I don't have the G-7700 anymore Big Mac does ;)

[BeatleFred]

Ok Thor, I'll let you know if any more info turns up on that model. I do know of a Sansui Online friend residing in Denmark- he's restoring a BA-5000, I'll see if I can email him and if he might know anything on them. B/F.

Basically you can look at it from several viewpts- your call though which option you think is best for you. B/F.

first, I wanted to say, you can use Microsoft Excel (or Lotus 1-2-3) it's a spred sheet, and although the inital trouble of entering all the info in, all you gotta do is type a model, say KR-8010 and it will show you everything in the data base (that you created) with that model in it, alot of people groupd their cd's like that also, there are in infinite amout of possiblities

also, Rob is giving it to me for free, he was going to throw it away, I just have to make the shipping arangments, he dosn't want to even bother packing it or anything, so it sent it to Mail Boxes etc.. and they are the ones doing everything, so I need to call them,a nd see how much it will be, single boxed with the bare minuim of everything, I mean it's is only about $25 to ship it UPS everything else is Mail boxes etc...

I told myself if it is $65 or close to it, I'll go for it, one of the first things I would like to do is add my own pre-out/power in, that shouldn't be too hard

Rob said he had it looked at twice (a friend that does that work) the first time when he got it back, the same thing was ahppening, the second time, it worked then the Onkyo that his son was using in his room went, and he started using the G-7700 and then the right channel went bad again

I think I'll go for it, like like you said, there are alot of differnt things I could do, and I would realy like to try and fix it myself, then I can say I fixed it.

but please anymore info and all will be very helpful, are these things really sought after? or looked at with the other junk (and I use that term freely) that was made in the 80's? IMO this is like one of the last classic Sansui's, and the guts of it are very plain but also it seems simple to work on

and finaly, can someone please also tell me what DC amp is, I know it is direct coupling, but how does it differ then a normal amp or my KR-8010?

[BeatleFred]

Perhaps I didnt mention it, I have been feeling a bit overwhelmed trying to keep up with my email correspondences and the postings on this site- been verrrry busy lately- my eyeballs are really straining... but Yes, it is my intention to put all that info in a computerized database. Which one, Access, File maker Pro, remains to be seen. I'll decide on that when the time comes. All I know I am going to have to tear myself away from this site somehow if I hope to make progress with that. Tonight is already gone- got home from work at 6:00, ate dinner, and then got onto this site and here Ive been for practically 5 hours straight. Up for Work early again tomorrow..... oh well, maybe tomorrow night I can get underway with that again (organizing all the hi fi stuff in the collection), plus much more I can think of to do- how can anyone ever be bored with themselves??

As for cd's: No need to log anything in. Check out: www.base40.com Just pop the cd's in the drive and the pgm automtically creates the dbase for you. It recently did it for the 1600cd's in my collection:)

The G-7700 is a fine receiver. Separable pre/power sections wouldve been convenient but theyre just not on the 9700...4700 Line. As I said before, ther are other Sansui models and some good deals to be had- the 9090DB is probably THE most popular Sansui receiver and the AU Series Integrateds are top notch. So you can consider those too- check out whats on Ebay and see what strikes your fancy. Why some have problems that need repairing I dunno.... in general they are very reliable. I'd never part with any of my AU integrateds, I can tell you that.

I'm about to nod off here, time to log off, next time I'll see if I can make DC clearer you, or if someone else might wanna try and give it a shot to save me the effort, but I thought I already did explain it to you. I'm not familiar w/ your Kenwood's circuitry to compare its design to Sansui's DC.

B/F.

[Night Wolf]

thanks, I'll check that site out when I get back home

I was thinking about it, and I'll probaly go for it, I will add my own pre-out/power-in jacks, that shouldn't be too hard.

I do like the 9090DB and the AU series, but I would rather snag a SX-1280 over a 9090DB

about the G-7700, from looking at the inside of it, it look's rather weak, like when compared to other Sansui's, such as no triodial transformer, and 2 caps, which look kida small considering what the amp is.

yeah, maybe when you get a chance you can explane DC to me, I know it means direct coupling, and heard that there are no caps in the audio signal, but I don't get it, it looks like any other amp and still has caps and all, so I really don't get it.

BTW, I know how ya feel, take your time, no need to overwhelm yourself over this, Thanks

[Night Wolf]

ok, I am now a proud Sansui owner!!!!

so I called up mail boxes etc... again, was finding other ways besides $80 for the double box and all, so she said for $50 they can drop the 40lbs. Sansui in a box, ad ship it for $50!, so 2 things came to my mind, first the Sansui which would leave in 1 piece from them, would arrive in about 3 millon pieces (granted you don't count the glass) and second, UPS only would charge $25 to ship it, and everything else is packing and stuff? (remember just 1 box)

so I went the next step up, it will be in the box, with 4 of those styrofoam corner things in all 4 corners (be about 1 1/2 inches of space from the box to the Sansui), some cardboard wafer things between the foam unit and box (after talking and being real nice she said she'll do that for free :D ) and $200 insurance brought the total to $60, so although that is still incrediably over priced, and crazy (remember $25 of that is going to UPS for shipping the thing) it is the best I could do, I wasn't going to spend $80 on shipping, and I wsn't going to just dump it in a box either, so this is ok

let's just hope it will go from Indinan to New York (gotta love NY) safley

BF when you get a chance, can ou make me a copy of the service manual, and do you have the user manual? then let me know how much you want for all that, and I'll send you a MO

[BeatleFred]

NW- Congrats on your purchase- I'll gather the stuff on the G-7700 and make copies.

Re: "weak"- far from it. Reread the 7/80 review that was posted here-especially the latter part of the review that comments on its power reserve potential. Re: "small": Is is that much smaller than other 120W receivers you've seen- or lighter at 40lbs?

There are decent-sized heat sink fins in the back and the G-7700 output transistors will ensure that the G-7700 can be driven to its full rated power of 120W per chan w/o the slightest trace of distortion. THD is less than 0.025%.

Re: DC- Direct Coupled. Of course there are capacitors in the receiver- there has to be, but in the signal path itself, from the AUX input, for example, thru the amplifier stages- onto the Output , there is not a capacitor in that path which could cause tonal coloration or phase delay problems. Higher slew rate, lower distortion, all of which serve to produce the best quality sound reproduction. Of course, to enable pure DC, you would obviously bypass the tone controls by activating the Tone defeat switch.

B/F.

[Night Wolf]

yeah, today while I was in school, and kept thinking about it, so I am saying to myself, well it's 40lbs. that's alot, just for compareion, my KR-8010 is 44lbs. and I am like that is built nice and solid, so that Sansui would proably be on-par with it (ITO internal compoents) or even better

yeah, in that review the thing did have some power, but why would Sansui only rate it for 8ohm, is it could handle 4 ohms with no problem, and only have trouble (due to the protection circutis) when almost clipped in 2ohms?

Thanks for explaing DC to me, now I get it, and es, for the most part I run my system with tone defeat switch on, my L100's do not need any tone or anything to sound good (although some older tracks need the highs and sometimes lows heled a tag, and sometimes when I am in the party mood, I just crank the bass, but for normal listening, no tone controls)

Thanks BF, I really appericiate you doing all that for me, when you are done, just let me know how much ou want, and I'll send a MO

Hello there again young lad, Sansui did make a point on their later models in the 80's- such as their AU-G series integrated amps, to list specs for power into 4 and 2 ohms. Back when the G-7700 came out though, that wasnt really the standard, in fact about two years prior, the Industry did a whole revamping on how to properly interpret power specs. Again, this can be an involved subject of which, I dont have the time now to type in a whole essay about. I'm sure in those stacks (and stacks) of hi fi mag backissues I have, there are good articles that explain the subject in detail w/o getting overly-technical about it- and when I find them I'll let you know.

I can tell you that my G-7700 has no problems handling my speakers - the incomparable Infinity Renaissance 90. Reviews say it all: http://www.audioreview.com/Main,Speaker/Infinity,Systems,Renaissance,90/PRD_119649_1594crx.aspx

I'm sure you've heard of Infinity but not that model. Trust me though, they are EXCEPTIONAL loudspeakers.

I also hope you are aware that just because an amp plays LOUD when its Volume control is '"merely" on 2, that it doesnt mean its 'like- super-powerful', right?

Later, B/F. (ps- You and Mr ProAc are going to have to simmer down, otherwise if THOR steps in and tosses some people thru the air, its all over:) (pss- Or if instead, THOR decides he wants to get you in a head-lock -fugeddddabouuutit:)

yeah, I am kinda uner the impression that the G-7700 is not up to par with more early Snasui, oh well, guess I will have to wait to actualy see it

yeah, they wont have a problem at all, although I really don't have a use for it, maybe if I actualy get it working, I will use it to power my woofers, and between my 2 KR-8010's, make 1 real nice one with the best of the best

yeah, I know all abou the volume thing, my little KA-1500 by the time you get to about 3 -3 1/2 (out of 10) it is already at it's max (little 20wpc jobber)

yeah I think the thing between me and Proac has been settled (through the use of PM) still kinda fuzzy, just alot of misunderstandings

about the Sansui though, I am really happy that I am getting a rather big Sansui G rec. but am under the impression, like I said, that it is not at par with the other Sansui's etc.... ahhhh I just wanna get it and then check it al out and stuff, I am kinda excited about getting it, it'll give me something to mess around with, I wonder though how it will stack up against my KR-8010, although I am hearing the tuners in Kenwood's are great. although the Sansui was $100 more when it was new (sold about the same time)

ah well, it's getting late, I'm gonna go to sleep now, talk to everyone tomorrow

Sigh..... what am I gonna do with you, Laddie... Havent I made it clear enough to you that the G-7700 is a fine receiver? So then why do you persist with this notion that its lacking compared to other Sansui models- I never said that. I might have to arrange to have Mr THOR put Ya in a headlock for yer own good.

As for Power/ Volume: I dont know if you see where I'm coming from either. I have a Sansui AU-20000 amp. Made in 1977. A real beauty. 170W- which according to its wattage makes it the most powerful amp I own. Yet, if I want to play music a lil bit more on the Louder side- I have to turn up the Volume control higher on the AU-20K than all my other amps- how can this be (?) with a 170W amplifier, your young inquiring lil mind might ask.

Well, its simply that the Volume control is in 3db increments all the way around the dial from left to right on the AU-20K: -60,
-57, -54.... and so on till 0DB. Compare that to other models where the rate of DB change is typically greater- such as: -60, -54, -48, -42, -38.... thus, to get to -30DB on the AU-20K requires that the Volume control be turned up past halfway mark whereas on the others, -30 DB is located at the 10 oclock postion. But make no mistake about it- the AU-20K IS powerful- it maintains the 3db increment whereas the others fall off, so while they peak out at some point, the AU-20K continues to pump it out. See what I mean, Laddie? And when I use the word 'pump'- please dont get yerself too excited there, ok? We'd all appreciate that:)

Power & Volume are not linearly related. Just like our Hearing. Its logarithmic. Good example: if you stand next to a plane on a runway that has say a sound level of 130DB- what happens if a 2nd plane came along and parked next to it? What level would your ears be hearing then? Answer: 133DB which is logarithmic. Not 130 + 130= 260DB which would be linear. Otherwise, if that were the case, your ears would be blown out by the two planes. Got it?

Anyway, enough lecturing. I suggest that you just wait until the G-7700 arrives and then you can let us know what you think of it.

B/F.

Yup, what B'Fred said!
I'll guarantee the G-9700 is one big mofo receiver, no doubt about that!
Like BF mentioned, I DO rather like it a lot. There, I've said it again. I'll most likely say I like in the future, too.
And, I'm not just comparing the big G with the other 5 receiver-based systems here, but also against the four (currently) BIG separates-based kits I have together.
I have the big Yamaha, Pioneer, Kenwood, Concept and Onkyo, besides the Sansui. A dozen big separate amplifiers. Between the receivers, really not a spits worth of difference. Choosing one would be choosing the one that just 'felt' right to the individual doing the picking. By that I mean the choice simply cannot be made by specs alone, they are virtually the same. The choice would be based on those intangibles of subjectivity.
Gotta be plain as the nose on Barbra Striesand's face that Sansui believed the G-series was an improvement on what came before.
Spec-wise, at least, distortion, for example, was way lower than the 9090's.
What does it all mean? Go with what 'grabs' y'all!
My subjective choice as 'best' among my group of receivers is the Concept 16.5.
To thine own self be true.
Eh, what?

no need to explain all that to me, as I already know/understand all that, and I know all about the volume knob, some people have the vibe that becuase the volume knob is only halfway, that the amp is only using half it's power, and it can get twice as loud or whatever they think, it's just another one of those things in audio that, for the mass consumer market, people don't know, kinda like how they think if your speaker says 300watts you need and must have a 300watt amp

what I was saying, was when I look at other Sansui's from a few years eailer, they had bigger triodial transformers and bigger caps, I am not saying the G-7700 is bad, or weak or anything, but saying it looks, er..... not as beefy then the other Sansui's

it should get here Monday, neat then I can see what's wrong with it, and start messing with it

[Night Wolf]

BF, do you have the user manual and the service manual for the G-7700 or just the service manual?

Thanks

[BeatleFred]

Hello Lad- I have the brochure, the service manual, and the operating manual. I made copies of them all earlier today for you-so send a p- message to me on this site, or email, so we can complete the transaction and I can mail them all out to you.

B/F.
