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?

I had my SA-100 upgraded in 2002 (run #4) to NP-100.
I've used the amp with an Acurus RL-11 Preamp, and Goertz speaker cable to drive a pair of MG2.6s and more recently MG20.1s.
IMHO its a fine Amp - I have had no reliability issues in the six years since the rebuild. I have gone through one set of tubes - that is a lot of hrs.
All the upgrades/rebuilds are absent MOSFETs - the primary culprit in Counterpoint failures.
Additionally, Michael Elliot is a pleasure to work with and he's responsive to queries.
I've got the last SA-220 to leave Counterpoint sitting here. It's running but I have used it in years. For what the AV mods would cost I've bought an RM-9 and an RM-10. I keep forgetting I have the SA-220 because the MRs just sound so much better.
Contact me for repairs or rebuilds on any Counterpoint product or any other product.

Happy Listening.
