I'm at a bit of a loss with this one, folks. There are two things wrong with it but I wasn't too comfortable attempting repairs on either issue.

This was my first vintage receiver I’ve ever owned and one of my favorites. I had it serviced by by Chicago Audio in Chicago and I use it almost every day, I enjoy it because of its simplicity and how nice it looks. It screams 70s more than most receivers. They are considered rare but not that sought after. Long story short, if you want a great vintage receiver for efficient speakers, this is the one to get if you can find one.
Quad was pretty much a Flop!, Started around 1971, Peaked 1973-74 and was pretty much gone by 1978, Good ole classic 2 Channel Stereo is the best! "1958-Present!"
I'm right in the middle of restoring a Pioneer SX-939 that I got last year for 20 bucks but it was a disaster case that was in a Cow Barn that needs total restoration. Lots of hay seed and mouse piss and shit all over and in the unit. When I'm done with that I got a Sansui 3300 I have to restore that I also got cheap 35 bucks but is in much nicer shape than the SX-939. Love your channel I learned a few things thanks.
That stereo was sold overseas on a military base PX. It had a 220v, 110v switch so service members could still use it when they got home. Sansui sold a lot of equipment like this.
The SSN being engraved was so that your equipment was not accidentally taken by another soldier. They engraved their SSN on their valuables on base to not lose them. Lots of guys bought the exact same stuff at the store on the base due to limited selection so it was neccesary to know who owned what.
Just came across this video.The 4-channel modes are designed to play QUAD records and tapes.Some stereo music can produce simulated quad effects, but the rear channels aren't as pronounced,because on the matrix 4- modes produce out of phase information. The Sq and Qs work better in these modes because that's what they're supposed to do. Records that is,quad records.The discrete quad mode is for quad 8tracks ,which requires
A 4 channel 8 track player
That is indeed a rare bird. About 3 years ago my Sansui 9090DB went down so I bought a Sansui QR-4500 Quad to tide me over until I got it fixed. Love that little receiver! On that one it has a "concert hall" setting that's great for live recordings & trippy stuff. Really opens the sound stage up.
A reverb unit also helps achieve that concert hall sound.
@@janicehopkins4432 Oh I've got a Sansui Reverb as well, but haven't hooked it up in quite a while.
Got 2 of them, and yes many of my 70s gear have electro pencil ssn or driver's license numbers.
Sansui AU 717. Best integrated amplifier under 100 watts ever made
What's up Aidan!, good to see you back at the bench. I had one of the Sansui Quads back in the day along with 4 Sansui speakers to go with it, worked like a champ and sounded great. Sold it to my sister in law around 1980, she may still have it. I was stupid young and didn't even know how it worked(technically), looked cool though. Good luck if this one comes back to you.
love it, i am a quad head. I have a Sansui QR 6500, Pioneer QX949A, and QX646, plus an old Heathkit with dual amps. Love the old steelcase desk, heavy beast. I would say have a listen to a good quad recording on a good quad system (properly functioning). Technically you need four of the same speakers. You can get old quad LP's and Tapes if you try. Quarter turn, Basically you are moving the speaker output around in a circle. Front left moves to front right speaker, Front right moves to rear right speaker, rear right moves to rear left speaker and rear left moves to front left speaker. Half turn moves everything again. (if i understand it correctly)
Yeah, it's a weird one. That was a big problem with lesser quad stuff:
Keeping the price down eliminated a lot of features that fancier models had.
The shop I work in dealt with one of this model a few times over the last two years.
It had enough little things wrong with it to keep the shop's owner frustrated for a while.
Nice to see you do a Sansui! Hopefully you’ll get a good one next…
I'm pretty sure if you tested the capacitors you'll find it's in need of a recap and possibly some transistors
Just replace it all and be done with it😂
in the 70's in my area we had one radio that broadcasted in quad. I also recently found a quad demo record
Sansui system used 'QS' for their quad decoding. There were so many quad systems, that's why it failed. You'd have to get something encoded in QS to get true decoding. Hope this info helps, of your interested ?? Quad is a whole can of worms!! Yes, the board you were not sure of is the decoding QS board...
Thank you for telling us the watts, can you please keep doing that for us amateurs.
Really liking your content and learning much. Thank you! I'm curious. Is that an isolation transformer on your bench? Just wondering what steps you are taking to not Zap yourself.
The two headphone jacks, there used to be quad headphones that had two plugs, two speakers in the headphone for each ear. I remember those.
I still have a working set, Sansui of course. Great on my QRX 6500.
I just bought more of these and once I saw your video, I realized my 2,4 channel light doersnt come on at all or neither does my fm stereo light. Channel light little box is burnt pretty bad. I would love for it all to work but looks very hard to repair.
Cats just looooove those spring toys.
SSN engraved + Overseas -- maybe military owned, and the SSN was used to help track it when shipped when the person was reposted? Just a wild guess.
Yes. This us EXACTLY it. It is also why there is a 220v/110v switch...so they could still use their stereo back home
If that's the case, that was no longer being done when I sent my stereo gear back home from Okinawa in '78.
When you shift the fase of one channel for 180°, the bass will always suffer because when one driver goes out, the other goes in, and the result is cancelling bass out. Just like switching plus/minus of one speaker.
Did not see you check caps in circuit. You could get an impression of the overall state of them. E.g. in circuit a high ESR is always bad. Since both channels had the distortion, starting with the PSU would be the way to go.
Thanks for another great video, Aidan!
Cool, I need to go through and service my uncles old Technics SA-8000X quad receiver that I inherited one of these days! It would be cool to have a quad setup, just for the heck of it.
I think this must be similar to the Dynaco Dynaquad circuit. Front speakers in phase, rear out of phase. Not true quad as we know it, just more of a special effect.
welcome back AH-FIX-IT.
I love quadraphonic, listen to Pink Floyd's Quadraphonic Dark Side Of The Moon and you will see why
Nice review! Just keeping it in perspective, would any modern receiver you would buy today be playing that good 50 years from now?
Very doubtful, Sir!
Please tell the kittys.....that we said 👋 hi!!!!
Isn't Quadraphonic attempting to decode an encoded signal, so it would sound different? Like enabling Dolby NR on a non-dolby signal. For a non-encoded signal that plays through all four speakers, would one would select 2 channel front + rear?
I get the impression that the resurgence of vintage hifi is starting to wane. I eliminate the obscene looking number butchered into the faceplates by sanding and rebrushing with scotchbrite or filling, priming and painting. I prefer not painting.
How do i do a dc offset on my marantz pm420 stereo amplifier ?
Kind regards.
You have gotten some interesting sound equipment from that source. Brave of you to share your journeys through the unknown. Is that the point when you started talking to your self?
As for this issue, I'm wondering if it requires an actual 4 channel source to work correctly.
I have a Sansui 3000A but it goes into protection mode when I power it up.
It might be that the lightbulb is just not in the right place in the lightpipe, that's why it doesn't work right?
just out of curiousity, if im recalling correctly you are in western PA now? is 103.1 near you WKVE?? if so you are one lucky SOB, 103.1 is fuckin amazing! and they don't stream. a close friend of mine lives out ion Oakmont, PA and one of the thing i enjoy most about visiting is listening to WKVE. the only Classic Rock station i know of that doesnt play the same shit songs over and over again.
Get rid of those ELNA caps....
Speakers off the bench and on the wall
Are you related to Gavin from the slow mo guys ? You sure look alike ;) .
👍
Отличный аппарат!👍
Yes, was there in mid 1970's and I of all people almost considered doing that metal engraving to my Sherwood, can't explain the reasoning for such stupidity.
That's a great point. It's like how sharing pictures and stuff on social media nowadays can give the not-so-friendly elements of society a surprisingly intimate peek into one's life. Yet...we love having cameras watching us in our homes and microphones listening to us when we talk. The silliness just keeps on keepin' on...
