I must say that for a 60's amplifier, this thing kicks butt! A solid, well-built receiver that does everything right...The tuner section alone is to die for and it picks up lots of stations...It is in my main system now and the guy I bought mine from was the original owner, who had it gifted to him from a brother stationed in Guam...It had been overhauled by one of the best audio shops in this area, too...So complete and perfect! It is a great conversation piece, I might add, and well-worth buying if you see one for the right price in your area...If you buy one, though, check to see if the replacement F6013 driver boards have been installed...Not a dealbreaker if they aren't, but they're good to have! IMO Sansui never really made a bad product in the late 60's-early 70's and this one is a crowning jewel in their line-up...A real workhorse AND heavy, too, but I love it!

I have to say, first of all, I wish I'd never loaned mine out to ANY relative. Long story short....left outside for a spring cleaning, showered rain for 10 minutes, replaced in a listening room, Boom! Fire....Oh the humanity!!!!! Last one I've owned in THAT condition....(before boom)! Never really knew how high the wattage was per channel....didn't care........I was pleased every time I turned it on! I would give this a 10 but they don't swim, LOL!! The years I owned it was during a time that I was introduced to the Sansui line and they have some good ones (IMHO) from the 60', 70's and then.....????? Not terrible! The WARM sound was only because the Bias knob in the back was always set lower for my floors sake and my hearing/placement of speakers/etc. I haven't heard anything that was as pleasing as this model since......Can almost put them in the same category as the G series (owned G-4700, G-120000 and 220000 ......too many zeros?) and couldn't find a favorite in the bunch...all good, IMHO!!
I'm still looking for a replacement that isn't considered GOLD to the seller and maybe I'll find another friend sometime that grows tired of his, LOL!!

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?


re: 5000A

I found a 5000LA earlier this year but have had no luck finding a 5000LA manual. Comparing the circuits of the 5000LA to the pictures in the 5000A manual I have found these differences:

The 5000LA does not have the circuit to switch between 120 volt and 220v. There's an empty space where the switch would be.

The 5000LA has the "new" 1063 power boards. I don't have a history on the receiver so don't know if the new boards are part of what makes it an "LA" or if the power circuits were added after market.

The front faceplate on my 5000LA says 5000A while the back of the unit shows 5000LA

Hopes these unofficial notes help a little bit. I have found very little info on the LA and none of it official.
