This is the very highly thought of Sansui 2000X. When working properly there aren't many receivers that sound as good as this one does within it's price range. It was produced from around 1971 up until about 1975 and puts out about 35 watts per channel. Quite a few of these receivers were made so they aren't exactly rare but the demand is high so they still command decent money on the auction market. A common refrain for this receiver is: Sounds bigger than it is!
The features on the 2000X are fairly basic but are all you really need in a good receiver. Here are it's basic features:
- signal meter
- tape in/output
- two phono inputs
- aux input
- loudness on/off
- muting on/off
- MPX noise canceller on/off
- low and high filters on/off
- selector switch
- separate bass and treble tone controls
One of the most commonly asked questions about the 2000x is what is the difference between it and the 2000A and 2000? Well, not a whole lot actually. The Sansui 2000 came first and the 2000A and 2000X were slightly improved versions of that model. But, the 2000 really didn't have any issues that required improvement. It's a good solid receiver and rated at 30 watts per channel. The 2000A puts out 32 WPC and the 2000X 39 WPC. Not too big a difference.
The 2000 has a different front panel layout with the push buttons in a different spot than the 2000A and 2000X. The 2000A and 2000X both have a MPX Noise Canceler button which the 2000 does not. There are also some minor circuit board modifications.
Design wise the 2000A and 2000x have full blackout across the face with a black tuning knob. Here is the 2000...
All of the 2000 models used somewhat lower quality capacitors which, if original, would probably be best replaced by now. Also, they are known for having some transistors that have gotten noisy with age. Specifically the 2sc458 transistors.
There are a number of modifications and upgrades that can be done on the 2000X. If you're technically oriented you may want to check out Conrad Hoffman's site where he details how and why to do the mods. Also, a good discussion on replacing the transistors is HERE (though it covers the 2000 the idea is the same).
The Sansui 2000X is a well regarded receiver. If you have it recapped and some of the upgrades noted above done then it will be a fantastic performer for you. Expect to pay from $150 to over $300 depending upon functionality and cosmetics. If you're going to upgrade it then look for a cheaper one that has great cosmetics since you'll be paying more to have it serviced anyway.
