Rebuild a Counterpoint SA-100 or start over?

I have a Counterpoint SA-100 hybrid amp that's about 13 years old. Recently I had to press it into service on a backup system. The amp is running noisy (hissing and hash). I changed the tubes, but the problem is still there. Maybe it has to do with the mosfet outputs. Anyway, I could send the amp to Alta Vista Audio and have the thing rebuilt for about $1,000. The guy that runs Alta Vista also ran Counterpoint before its demise. Philisophically, I do have a bit of a problem sending the amp for a rebuilt when the guy didn't do such a great job in the first place. The alternative is to just buy a new amp. It would drive a pair of Quad 22Ls. Any suggestions?

If it's a MOS FET amp, I would recommend you contact Frank Van Alstine for pricing info. He has been doing great work on Haflers for years and years. I believe he does a nice job on rebuilding earlier Dynaco tube amps also.

I'm with Elizabeth. A kilobuck is too much to rebuild your amp. You can buy McCormack DNA1 right now hear on audiogon fur much less and will probably be happy or even happier than with Counterpoint.
The MOSFET outputs in Counterpoint either work or don't so more-likely you're in OK shape on that issue. Replacing electrolytic capacitors and protection relays will probably eliminate problem.

The SA-100 is a power amp, not a preamp, and is definitely worth more than $500 when its rebuilt. You can certainly get fully working original SA-100s and SA-200s for around $800+, but they are not the same thing as the rebuilt units.

When Alta Vista rebuilds these units, they're not a rebuild-in-kind. They're basically a replacement of most of the electronics. Because Alta Vista operates on a very different business basis than Counterpoint did, you get a considerably higher value out of the rebuilds than the original units.

Most of the Alta Vista rebuilds are VERY extensive and QUITE expensive - the maxxed out rebuild of an SA-220 runs $3200+, plus the $800+ you put in to get the original unit. (There are less invasive $1500 rebuild options too.) I've heard the upgraded SA-220 and SA-5.1s, and they do sound REALLY smooth, but at those price points you have to consider a lot of other things as well, and the competition is quite stiff at that level.

However, the $1000 rebuild on the SA-100 looks like a pretty good deal, since the result (based on the SA-220 upgrade) is likely to be more than competitive with anything you can get for $1000-$1500.

I had a Counterpoint SA-100 4 ,3 years and it leaked current to y speakers.I had it rewired and it did not sound as good as bvefore.BTW Counterpoint rewired the amp.It lost its depth somewhat but still sounded great.
