Hate to say it, but it might be cheaper to replace than repair. Don't feel bad, my first stereo was all Technics, bought one piece per paycheck, working construction when I was 17.

Kurt, do a Google search for it. This came up for me:

http://www.vintageaudiomanuals.com/-T.htm

as did a number of others. Finding one for free may be difficult or impossible, though.

Also, not to be patronizing, but did you check the balance knob? If so, maybe check to make sure that the knob is actually turning the control underneath of it.

There's also this for $97:

Probably a bad solder joint. I sold stereo stuff made back then, and even though the Technics stuff was better than most of the others, sometimes there would be one that lost a channel when one would crack or age. Some of the soldering I saw in Sansui equipment was amazingly poor. Pioneer and Kenwood had some problems with soldering too, especially in the lower end stuff. Sansui had issues with almost everything they made. They had a lot of cold solder joints on volume and balance pots, and sometimes they would "forget" to solder the speaker terminals at all!

They used to do a lot of wiring channels in reverse on tape decks too.

I got very good at finding bad joints with my fingers to get things humming while powered up, and a jewelers loupe to look for cracked joints..

At the age of a SA-404, I would look at electrolytic caps as my main component failiure possibility.

a jewelers loupe

I am guessing that is a bench Light, "a jewelers loupe".

I have looked all over and it all seems to be in Tact. I Agree it is a bad Componant.

If I can locate a Repair manual on the section "Audio Output" It would be a breez.

I will continue to look for a BO solder Joint or Cap.

Thanks. KK

Hmm?

A jewelers loupe is a jeweler's loupe:

VERY handy for looking at solder joints. Cracks that are invisible to the naked eye are easily seen with one.

That's to small !!!!!

Thats like trying to hold onto these new small cell phones. ~

I have a 12" Magnfing glass lighted loop. It helps and just like you say you can really see everything.

It does seem a bad componant is cousing the problem, Still need documentation on the audio out cir.

Thanks, Kurt

hey guys just happen to stumble upon your forum,i was looking for some manuals also, but i have two of these sa 404's, was looking to get them repaired,so i can then put them up on ebay,but i don't think i want to go through the hassle. both power on but no sound is coming out, i know one unit blew the amp ic's the other, the relay that turns the unit on. (you know that second click when you turn the reciever on) so anyway i'd give them up for something reasonable,im sure there is someone out there way more familiar than i am at repairing these units,that's all if anyone is interested,by all means let me know.god bless.

Welcome to the forum, Olivar!

I see non-working electronics on eBay all the time that are sold as-is, so that's still an option for you if you don't find anyone who wants them here. Sure, they'd fetch more if they were working, but I don't know how much those are worth even in working condition.

BTW - official rules for selling gear here are that you do it in the "Classifieds" section, and you need 25 posts to do it.
