Broke down and got the one at the thrift store for $5.00. (for $5.00 WHAT THE HELL) Missing a knob or 2. One speaker wire plug in is broke. Was told that it powers up. Will do a dc offset check this weekend and see if is still putting out... Question is should I look to fix up if I got a live one??? Found some info that says it was made in 83 and was only sold in Japan... Guess it is 100 to 125 WPC. Comments please....

These SX-9, SX-6 models were in the Line that came out after the SX-3900..3400 generation. I think they were already out by 1981 based on ads Ive seen in my collection of hi fi mags. There is a Year/Month date code to the Pioneer's, so you can always check your serial # in the back to determine the manufacture date.

These SX-9, 6.. models were a big change from the previous SX generations.

B/F

Not listed in Orion, but, jeez-willikers, not a bad deal for a TOTL receiver from 1981-83. Prolly 'bout 120 or 125 wpc. The SX-8 is 100 wpc.
Hope she puts out! :cool: ;)

Will shoot some pics on friday.

S# on back is DI or 1 2907472S

Max power consumption is listed as 300 W

It weighs a TON!!!!

Will open and take a pic or 2 also...

I have an SX-6 that is the worst freakin' 40wpc you ever heard, and it seems to be working just fine.

Hey TA,
You gotta stop holding back, man you're killing me.......
:D :D :D


Retro

My pleasure man. It IS a real dog. Electronic volume control and all.

TA

TA,
Well then, I think it's been a real pleasure never to have heard one then. ;) I think I'll just stay in my 1970's comfort zone. I've got a nice pair of Polk Monitor 7's all lined up for your old office set up. :D



Retro

That's going to be a nice office system. Polk 7's are great.

TA

here are some pics of the monster, front, back, then 2 nudies...

back

nudie... have no idea what all this stuff is...

last one....

That is one very nice receiver. Very advanced for its time (electronic volume control, computerized scan tuning with memory, etc). Never saw one before now. Hate to think of what it must have sold for when new. This receiver has all the functions we now take for granted in modern hi-fi gear. Did this receiver have remote control, by any chance? As sophisticated as it is, it wouldn't surprise me if it does.

no remote..

Got sniped by 1$ on ebay for a twin that went for $51.25...

Should have bid higher:(

In a word - Awsome!

My experience with this line was a lower model, forget the model number. But that, coupled with a Yamaha CD changer on one end and a pair of B&W 801's on t'other produced my first "out of the speaker" experience. An incredible amp.

Oddly, I've heard that line all but trashed by some; if only they could have heard that combo on some good classical...

Also, a hell of a classy looking bit of kit IMHO.

Congrats, mate!

Sorry to hear you were outbid for another SX-9 on ebay. :( I know the feeling. I bid on a Zenith radio last year and also (!) was outbid by a measly $1--but that's the nature of auctions. I eventually found the set I was looking for in another listing, however, and got it, as I was the only bidder on it.

I didn't think your SX-9 had a remote; couldn't see any kind of window on the front panel for a sensor, etc. It just occurred to me, as I looked at the pics of your set, that such a sophisticated piece of audio gear, years ahead of its time, might have one with the remote sensor hidden somewhere on the panel.

BTW, what you show in the "nudie" pics of your SX9 are the circuit boards, power supply filter capacitors, heat sinks for the output transistors and a good part of the receiver's internal circuitry. I don't know if this explanation means anything to you (have no idea how much you do or don't know about electronics), but if you do understand what I'm talking about, I hope the explanation helps. If you don't, please stay out of the cabinet of that receiver and refer all servicing to a qualified technician. There are high voltages present at practically every point on the chassis even when the set is turned off and unplugged, which can injure or kill anyone who doesn't know what he/she is doing.

BTW (2): It looks to me as if there is a fuse missing on the power supply circuit board. I never saw any kind of hi-fi gear with so many fuses. It must have separate fuses for each speaker and the output stages as well--but then again, that's Pioneer for you. In high-end receivers such as the SX series and others, they apparently didn't skimp on quality or protection.


Kind regards,

Jeffhs

I posted the nudie pics for those that are more in tune (no pun intended:) ) with the inerds and the like. Looks like a bunch of wires and stuff to me:) Did notice the one fuse missing???? Also noticed that BIG round thingy in there also:). Been picking up some of the lingo... Like CAPS... Saw the 2 smaller ones and was thinking if that HUGE one (4 or 5 inches accrss) was a CAP, it was one hell of a CAP:). I may have to haul it into the house on Sunday and hook it to some speakers and see if it works, but I dont want to blow out my good speakers... My luck and I blow up he house instead:)

The day I can afford $5,000 speakers like the B & W 801's, which WERE the top of their line at one time, you can bet I'll be able to afford driving them with a bit more than $200 worth of 40wpc receiver.

TA

That huge round thing is the transformer. Toroidal type at that! Them ones are supposed to be the goodun's...

Thanks Bolly..

Toasted Almond,
I seem to be in a new neighborhood for myself as I think this $5.00 reciver is rated some where between 100 to 125 WPC. have one GOOD set of Sansuii SP-Z9II's that I have been hauling around from 1985 and that is it. Dont want them puppies to go KABOOM:)

OMI,

Just make sure you have fun with the new territory. If those speakers don't have liquid cooled dome drivers you may want to watch yourself with the volume control, although I figure it'll get pretty loud and raucous before permanent damage sets in. For $5, EVEN I would have bought that receiver. I just never would've considered hooking it up to B & W's old flagship speaker.

I must admit to having learned SOMETHING on this thread. If B & W 801's can sound good driven by a bottom of the line, low powered receiver, it's a revelation. No WONDER why Yorx, Soundesign, Electrophonic, and kabuki speakers have never sounded good to me. I've only been driving them with Carver, Adcom, Onk, Dynaco, and a few other lesser amps. I will need to get a Krell, Rowland, or Boulder, and stop walking by all those gems in the thrift shops.

TA

Toasted Almond,

I have fallen into a few good deals recently after I started to unpack ALL my old stuff.... UNpacked up from my move to where I am at now in '94. Have a dinining room starting to get full of mid level stuff and a wife that is starting to make noise:) about it. The SX-9 may be one of those good deals. Not sure yet... I have 2 DSS-9 speakers in the garage waiting for the woofers to come back reconed. Speakers were $5.00 for the pair. The mids and tweets are supposed to be good. The woofers were SHOT.... I did some lookin' around and found ONE place in Florida that said that they had a few replacement cones still in stock. $75.00 per.. so $150.00 for both plus shipment cost. If all goes well should have 2 quality speakers for under $200.00 for the pair... And may get one more SX-9 if all goes well.... Gotta stop getting all this stuff...:) Have found some other good CHEAP deals at a thrift shop and could not pass 'em up. While mid level stuff.... But at $4 or $5 each WHY THE HELL NOT:) I think I am becoming an ADDICT... Help!!!! Is there a support group I can go too????? My knowledge on this stuff is ZERO but I am having fun:)
:)

If you've got the inclination AND the disposable cash it's harmless.
You have to watch the wifes "space" a little, and then start to develop a sense of which ones to walk away from, even for only $4 or 5. The stuff piles up in a hurry.

If you look anything like your avatar..... you have other issues that need attention far more than your impending mid-level audio addiction.

Somebody had to say it.

NOW FELLAS>>>
The dress WAS roomy and comfortable...:)

:banana:

Jersey is one thing dude, we've got/seen it all. But you go out the house looking like that in Alabama and it's probably gonna be a rough ride.

Too funny. . . I thought the same untill I read Mimi's thread about his/her halloween getup for the company halloween party. . .

Full view . . . . Funny stuff

MiMi draged (No pun intended) the SX-9 into the house and hooked it up to the sansui SP-Z9II's and am listening to NPR.. Thistle and Shamrock now... Sounds good... Had it to 14 on the sound level and it was booming!!! Wife was yealling.. TURN IT DOWN!!!

Hay Fellas ALABAMA just aint for red necks anymore:)

I dont know if I would tell anyone I lived in Alabama. . . . LOL. . . I used to live in Americus, GA and worked out of Cullman, Alabama . . I fly into Montgomery every couple weeks to go to Albany, GA. . . Only 300 bucks round trip compared to over a grand to Albany or Atlanta. . . 3 hour drive. . .

O.K. Got a question. There are 2 switches on the back of the SX-9. One says FM DE-EMPHASIS with selections of 50us and 75us. The other switch says A.M. CHANNEL STEP and the selections are 9KHZ and 10KHZ.

What are these switchs for and what do they do????

Thanks...

Leave the FM at 75, the other is AM. . . I dont know which one for that. Has to do with overseas and our FM/AM. . .

Set the AM switch at 10 and leave it there for use of the tuner in the United States or Canada. This switch determines whether the AM tuner will operate in steps of 9 or 10 KHz. The 9 KHz setting is for use in Europe and elsewhere overseas where the AM broadcast band's channel spacing is 9 KHz, i. e. their stations are not on even-numbered frequencies. That is, many European AM stations will be on oddball frequencies such as 871 KHz, 1041 KHz, etc., whereas on this side of the Atlantic our stations are on frequencies such as 870 and 1040 KHz. (9 KHz spacing as opposed to 10 here.) My Aiwa bookshelf stereo has a setting for this also (perhaps for the FM channel spacing as well), since these units are also widely marketed and used in Japan and other places with 9-KHz AM channel spacing, but the "switch" is a special keystroke sequence to set the tuning interval for the digital tuner; it is cleared and set to the 10 KHz default as soon as the power cord is disconnected or there is a power outage. "Out of the box" the channel spacing defaults to the North American 10-KHz standard, so the tuner is ready for use anywhere in the US with no further setup.

The 75/50 us switch modifies the FM de-emphasis time, as noted. The 50-us setting is for European and other overseas FM standards. Gyusher is correct; leave the FM switch set for 75 us, as this is the North American FM de-emphasis standard.

Kind regards,
