Posted some pics a couple weeks ago of a Goodwill G-4500. Well Cleaned it up and did a check out, only to find that the outputs were blown, however it did work fine with headphones.
For about $15 in parts, both sides of the amplifer were totally rebuilt. A full alignment was done,
Got it hooked up to a pair of Pioneer HPM-40's and it's sounding very good indeed.
I still think that Sansui has the worse service manuals.

Punker,
The G4500 cleaned up really well and looks great with the Pioneers. I've got the G3500 which I play around with every now and then and think it sounds pretty good for a small receiver. Well... it's the only receiver I have. :)
cheers

Here's a pic of it.
Nice job, love those big knobs :) I always liked the G series styling better than my 9090. If you think Sansui sevice manuals are bad you should see one of my Kenwood service manuals, the schematics are poorly laid out and too small for my old eyes.

Congrats, Punker, that Sansui is beautiful!
I really like your 'straight ahead' photography, too. It's a welcome change from all of the extreme angles commonly used. ;)

Punker, how did you get head on pictures with enough lighting, but without the stupid glare thing from the flash?
"I still think that Sansui has the worse service manuals."
why would you say that?
"If you think Sansui sevice manuals are bad you should see one of my Kenwood service manuals, the schematics are poorly laid out and too small for my old eyes. "
hmm, I have the service manual for my KR-8010 and now my G-7700, I'll have to compare each of them and see which seems better
"I really like your 'straight ahead' photography, too. It's a welcome change from all of the extreme angles commonly used. "
oh, ok I see where this is going, someone dosn't like my sleek side angle shots, yeah I see how it is now :D
yeah well, I have that stupid flash problem thing, I tried using a tissue in many differnt ways to defuse it, but it didn't work, oh well, I have a 6 1/2" tripod, real nice little thing, so I'll have to get a picture, turn the flash off and set the shutter speed to like 15 seconds or something, that will come out real nice :D

BTW you just gotta love the PURE POWER on the front of it :D
the inside of my 7700 is kinda depressing, as it's nothing special, but it sounds very nice (actualy I think it is the best sounding amp I have) and I read in the Stereo Review it really did like 180wpc, ahhh I can't wait until I get replacment LE25's for my L100's then I can hook the Sansui up to them, and just flat out crank them
becuase I gotta decide if I am gonna keep my dual KR-8010 setup, or run the 7700 alone, I just don't know if the 7700 will be enough for my times when I like to crank the system (I would have woofers go to spekaer a and midrange/tweeter to speaker b) or maybe use the Sansui for the woofers, and between my 2 KR-8010's make 1 real nice one and drive the midrange/tweeters with those, then I gotta decide which pre-amp/tuner to use, the Sansui or Kenwood, I really like the Sansui's pre and knobs and all better, but I heard the Kenwood has a better tuner
ahhhhhhhhhh too many choices, more is less is true

Don't use the flash, If you do, set your flash level at low and take the pic from a distant and zoom in. I use a tripod with no flash and use natural light. I set the camera to night +. ...
As far as Sansui manuals go. I could go on and on. One thing is no circuit discriptions. My G-4500 describes one circuit. A speaker protection circuit that prevents the speakers from popping when you turn it on. Well my speakers were popping. I go into the receiver looking for a certain cap. Guess what, its not even installed. I installed a cap. No more popping.
Their tuner alignments are absolutely redicutlous. The three Sansui Turners I've aligned, I ditched the manual and winged it and just used it as a guide as to what to adjust.
On their schematics they have a habit when a connection leaves a board they put a lettered tag and you have to go searching through all the scats to find out where it goes to.
As far as Kenwood goes, I've only seen a KR-9600 manual, and it had extensive circuit descriptions and the scats were easy to follow. I'd like to see a few more before I pass judgment on Kenwood.
I guess I'm just spoiled on pre-1979 Marantz manuals. After 79 they are just as bad if not worse then Sansui.

yeah my flash is either a on or off thing (I keep it on auto mostly, and it also had red eye reduction) I notice if I zoom in from a distance it's better
hmmm, I didn't look through my 7700 yet, I'll have to, I have gone trough my 8010 service manual, and it seemed to be real nice, but I didn't spend much time on that either

Hi NW- Yes- April 79 on your G-7700 and I was a freshman in high school at that time:) My G-7700 is only a month older than yours.
I have a G-5500 too by the way. The G-7500, 5500... is the 2nd Generation G Line. What I like about the earlier ones is that the pushbuttons are wider- more square shaped than they are on the G-9700...4700 Line, which are thinner- more rectangular shaped. I also think the G-"500" Series has a gorgeous tuner display- a lighter color than the "700" Series with beautiful AM FM number printing.
The Sansui logo is absolutely cool- as it illuminates, being inside the front tuner display. The logo size is larger on the 500's. I dont know why they cropped the size a wee bit on the 700's.

Its the not the best photo, but on the G-5500, the Signal & Tuning meters are located Above the AM/FM Dial.

NW- Maybe if you really get into collecting Sansui models, one of these "big bracioles" will come your way:

X, I stand corrected on some of the Kenwood service manuals, I just remembered that I had an old Kenwood model Eleven manual and it was very well laid out with clear schematics. The manual I was talking about was for a not very vintage KA-127 integrated amp. I also have a Sansui model 2000 receiver manual and I thought it wasn't to bad. I would say that the quality of the service manuals will vary for different models and years.

yeah I noticed the differnce between the X500 and X700 series
I really like the black face with white numbers, over the white face with black numbers, I just wish Sansui actualy made the LED power meter display on the 7700 somewhat decent (like 5 LED's to go from .1watt to 5watt, then a 25watt and a 120 watt.they should have add a 70 or so, and then a 180)
I noticed that with the pushbutons also, I just wish the buttons on my 7700 wern't made of plastic
yeah, the Sansiu logo is real cool, for some reason the 2 lights that light up the tuner dial thing are alittle weird, sometime they wont come on or only one does, in that case I have to hit the side of the case, and it will come right back on.
at first I didn't think I would like the digital display, but now I really do, and I actualy never use the analog dial to tune in the station anymore, BUT what is real neat about it is is has a full analog tuner and variable capacitor for the tuning, just as a normal analog tuner, but it has a digital display.
also, thanks for those pictures, real cool, man I would love that big Sansui, but were talking big $$$ there

I think the earlier Sansui manuals were alot more detailed as far as test procedures go.
