Picked up a Sansui 350A - any info?

[lungin]

Picked up a Sansui 350A on ebay here in the Uk - needs some work - had broken speaker switch which I have repaired. Also needs 'Stereo' bulb and 3 lamps for the tuning dial - are these a major headache to source?? Anyone have info on this model - had a look around AK and there doesnt appear to be much about it.
and finally the serial number for the data base : 820100944
Cheers for now!

theres some info here lungin, in Morden2004's Sansui database. http://www.clarkeworks.com/sansui/Ge...Model%20No.pdf

thanks for the info Bolly - I will continue working on it and will post photos of innards if anyone is interested. Also, has anyone any idea how to breath life back into the tuning needle/pointer - it should be lit up but at present it is deader than your average Dodo...

If you eventually need service manual and technical bulletins LINK

I just bought one at a charity store for 40$ with a pair of
Acoustic Research TSW 110 speakers and the owners and
service manuals. Witnesses said my eyes popped out
and jaw hit the ground. What would you like to know about
it? I could scan some pages and email them to you.

Hey that's a good haul!
What I am after is the schematics for the the 350A - want to try and give it the once over plus find a replacement for the 'needle ' bulb on the tuning display.
Any info you have would be cool
Cheers

I answered a listing on CL last night, was first in line, and went out and picked up a Sansui 350a on the eastside this afternoon for $20. I had a nice chat with the seller and his son who are both gearheads. He had a nice pair of Vandersteens and a very old pair of Thiels too. I've never seen one of these 350a units - 47 WPC from what I can find researching this unit, this one is in good shape and the controls were clean, just need to replace the tuning display bulbs. It's always a good day when you can bring home another nice Sansui

Here's a few pictures:

The 350 A was the heart of my first component system and If I recall, I purchased it used from an older guy in the ‘hood for $100. More like 20 wpc I think. Fond memories of that one and have considered picking up another simply for the nostalgia. Wonderful little unit. I gave it to my Dad and it started acting up, which was probably just dirty contacts or pots, but it did not have a happy ending...long before I got back into this stuff.

[SpeakerLabFan]

Ah, thanks for that info. I found the spec sheet and you're right, 20 WPC into 8 ohms: http://www.classicsansui.net/images/...350A/350Ab.jpg

[Bigears]

That was a big 20 wpc as I recall. My 6X9" Ampex speakers (yes from a tape deck) rocked pretty good with that unit!

I have an Orion book and it shows the 350 and the 350A, and both should be 30 watts X2 RMS. I just put one on ebay, and it is pretty and works fine. The controls do get corroded and need a good cleaning. At first, I thought the left channel was out. Nope, just dirty contacts.

Well, I've just picked one up yesterday for very cheap. I'm really happy about the tuner quality. It is FET driven and has 4 gang and 3 filters; very very good sound. It will get the 1rst home place as soon as I will have replaced the capacitors. It seems to miss some punch in the bass according to me. I will increase some values, specially the caps on the o/p . By the way, a 2200 on the A/C filtering is the smallest I've ever seen... Were they missing money from the FET on the tuner side ?

Anybody know where to find the schamatics ?

Thought I would bump this one more time and see if I can get moving on this baby. I've had it awhile now and finally have a clear space to work on its assorted problems. These amount to a permanent background hiss on the right channel - even with volume down to '0' or balance set fully to left channel; pops and cracks come on within 5-10 seconds when she is switched to AM setting; Blown needle bulb on the tuning dial ( can these be replaced with a suitable LED?)
Of course there is the usual need of a schematic /manual - there isn't a whole lot of info on this model - maybe as it is marked on the back as European - any of you guys have experience off working on one?
She is nice receiver with a proper wooden case and I just want to breath a bit of life back into her, make her sing again!
Anyway, over to you and cheers for now...

wow that thing looks very close to a 1000x, but appears to have fewer inputs/oututs on the rear. Have you tried deoxit on all your controlls yet? I have a 1000x, and those stilly lever style switches can be a pain. You have to take off the face of the amp to get to them to spray deoxit in them, and the tape monitor switches seem to cause a lot of trouble when they are dirty. Mine didn't pass audio untill I did that, which is probably the reason it got donated in the first place.
The needle "LED" I think is really a minature peanut bulb isn't it? I think theres a source on evilpay for those, also some for the fuse lights too.

Thanks for the reply - I've cleaned all controls and switches with deoxit awhile back but the problems are still there - when you say peanut bulb are these available still - Radioshack? or the UK equivilant -Maplins. Will have to check that out. I shall also check out the 1000x and see if its a similar model
cheers man
