I have a few Sansui Integrated amps and receivers besides this one. I saw it listed on Craigslist a couple of months ago for $60. It was built in 1969. Seemed reasonable enough. Kinda dirty. but cleaned up nicely. Let it sit for 7 weeks before I hooked it up. This one has a damping selector on the back. Low =15, high =30. Been playing it for a few days now. 1st aux streaming spotify premium, right now the phono is blowing me away. Have it matched up with some nice CS 77a's. Thought I was going to take it for service, not knowing very much about it's usage history, but I think that can wait. Pretty impressive little amp. A few FM stations come in (basement) without antenna. Everything works and sounds very good.

My collection is mainly marantz. Bought this 5000A about 6 months ago and had it repaired. Finally hooked it up to replace a 2275/marantz while having a few lamps changed and I'm very impressed with the Sansui. It sounds a lot like a marantz,,,I won't say better b/c I am such a marantz fan. I don't think it looks as good as 70's marantz but it sounds as good. I like the fact when I switch to aux the dial lights go out. For 55 wpc of the vintage juice this thing rocks and it's quality audio. Nothing distorted and plenty of bass. I've had a few Sansui but very few. I've got a B-3000 amp,,,this is approx 10 years older and sounds better. I bought the 5000A w/a marantz 2270 and sold the marantz (already had one). Glad I kept this 5000A,,,it's a keeper.

Schematic is incomplete. Both parts are duplicates of each other. Anyone have a schematic?

re: 5000A

New complete schematic has been posted.

re: 5000A

Anyone familiar with the Model 5000 LA. Is that possibly the designation for the factory upgrade of the board?

Thanks
