Sansui 2000A

Hello all-Anyone out there have an opinion on the 2000A?
Seems to be some at pretty resonable prices.
I am looking to use as a pre-amp in my main set up.
Later will be the main in my bedroom system.
Low power (35wpc) I know but how do those 35 wpc sound?
Thanks

The 2000a is a fine receiver, probably one of sansui's best low powered at the time. If you plan to use it as a preamp, I would highly suggest replacing the old electrolytics in the preamp/tone board with some high quality low noise caps.

That same board is covered with 2sc458 transistors that will become leaky and cause a high noise floor. If you have alot of hiss or static at no volume on any input, chances are one or more is failing. A very good replacement for them is a 2sc2240.

They are great receivers for a bedroom setup. The 2000a also has a wonderful sounding, and sensitive tuner.
 
Thanks Jordan. I see on the epay auction site that they have one "buy now" at $75 ($30 shipping) - From my search on AK that might be a bit high.
It does say its been cleaned and new lamps. What is a fair price? $50?
 
Thanks Eddie/Jordan-I think I'll see how much it will go for -It is a very clean piece and everything I've been able to find on it sounds very positive.
 
JP Dylon restored a Sansui 2000A in an excellent looking wooden case. This one is a gem. I have it for sale at $279.95 in my customer lobby. I might let someone bargain me down to $259.95 -- but it's worth every penny.

The $50 - $75 ebay machines that "work fine" or similar, are usually mega-BS. The charming, good-as-new, fabulous, wonderful, mint, gorgeous machine with the touched-up picture that sells for $100 including shipping really needs $100 - $200 in repair to be a reliable instrument -- only you don't know this until you open the box and try it out.

I have 2 of them I paid $5 each for at yard sales, so there are deals out there. My 5000 was more, but I got the Sansui a Dual 1019 TT, and a couple of records for $42 (all I had at the time) from a guy that tried a couple of times to get more at yard sales and never found a taker.

Deals are where you find them.

I tend to agree with Fred somewhat, it is a crap shoot. one might work and look perfect, another might die 1 hour after you get it going, and that does not necessarily mean the PO knew and palmed it off on you. Older long term storage electronics gear does die...

that was my 2000a i had listed for 75.00,every cap has been replaced on EVERY BOARD,I pulled and ended the auction after seeing this post about my auction,75.00 was a fair price considering the time it took and parts.

Hum, I'm confused. I agree, $75 sounds like a more than fair price for the unit you describe. I haven't seen anything in this thread that would suggest otherwise. Shoot, I'd say that's a great deal. Sounds like you have a potential buyer here too. Clearly, as usual, I've missed something.

This is what I think.

I took a look at the auction and your 2000A appears to be a very nice unit.
I understand that after all the work and parts that go into a receiver, you feel you should get a fair price. I do not know what your reserve was, but I would guess bids would have reached about $50. Not that your receiver is not worth more, but they just do not sell for more, usually. I bought a 2000A for $10. Yes it had the wood case. It is a great little receiver. I picked up a 4000 for $5, with wood case. Both in very good condition.
for someone who hits the flea markets, garage sales, and thrifts I would not pay $75 for a 2000A. I also can repair one or recap it.
Now, for a person that does not spend the time to go out looking for the deals, or can't do the maintenance, I think your 2000A would have been a great buy.

I sold my 2000A but will keep the 4000 because it's worth more to me than I could sell it for.

I have an AU-555A that when all is said and done, I will have many hours of labor and many dollars of parts into. I will lose my shirt if I sell it. I did the work to keep it. I cant expect someone to pay me $200 for a $75 (if I am lucky) amplifier. It is nice though.:yes:

Hey Wiseguy-I wasn't ruling out even the buy it now price at $75.00
As I posted I thought it looked very clean but I don't have any experience with sansui model. After Longworths post stating that he had the same model at $280 I went back to take another look at yours but it had been pulled. Honestly I thought I lost out that some one beat me with the "buy it now".
If you are still interested in selling pm me and we'll see what can get done.
 
After searching for information about my new found friend, a Sansui 2000A, I stumbled on this thread. I have done quite a bit of reading but have more to go. I know that it has been sitting unused for about 15 years so I powered it up very slowly with a variac. I am not sure if this is the best place to post this or not. This receiver will clean up nicely but I sure would appreciate having the DC bias and offset adjustment procedure for this gem. It seems to sound fine and it does not run hot. I do see the trim pots on the main amplifier board but I am not sure where to connect the meter(s) and what the idle current should be set to.

Thanks in advance. Any help will be appreciated.
 
No offset adjustment for the 2000a, but there is a bias and center voltage adjustment.

First, Measure the voltage from the collector of the transistors and ground on one channel. One transistor will be a higher voltage, the other about half of the higher voltage (so if the collector of one measures 70v, the other should measure about 35.) If it doesn't adjust VR-01 (smaller pot) until the lower voltage is half of the higher. --clear as mud?

Next, set the idle current by connecting your meter across the emitter resistor that is connected to ground. Use VR-02 (large pot) and adjust for 12mv.

The final step is optional, but will make for the best fdelity:

Connect the receiver to a scope and an 8 ohm load. Induce a signal until the output just starts to clip. Then go back to the center voltage pot (VR-01) and adjust for symmetrical clipping.

repeat with the other channel.
 
Say, I just saw a 2000A at Goodwill for $50. It's tempting. Is the power really 90 watts at 8 ohm? What year is it from? Looks to be in decent shape cosmetically, but I didn't test it in any way.

There was another Sansui there, though I didn't get the model # as it had a broken power lever ($20 "As is").

[Edit] Found elsewhere that it was '71-'75 and 35 watts.

[Edit II] Also, how difficult might it be to find a new power lever for a broken one? It actually looked in decent shape otherwise.

This sounds like the problem I'm having with my 2000X. How much should replacing the caps on the preamp board cost? I'm getting a low-level hiss in the left channel. I really want this fixed, I love this receiver.

It's the transistors, not the caps....

I get it now, The Korvettes pic is in your sig. K
 
Is the fuse in the "100-127V-3A / 220-250V-2A" slot on the back a common one,, or difficult to find? Probably a stupid question, but I'm new to the game. Got mine for $20, hoping this is the only problem because it's fairly clean. Looks like it has been sitting in a box for 30-something years.
