Counterpoint - Alta Vista - Mike Elliott

I was just informed that Mike has stopped all business because of health reasons. The Alta Vista Website confirms this. I know some of you may have had some issues dealing with Mike in the past but Mike was always a professional to me and accommodating to all of my dumb questions. I learned so much from his designs and I know that they were way ahead of their time. I just finished modifying an SA-5000 for a few audiophiles based on the information provided on the Alta Vista Audio website and they sound excellent. I still own the current version of the NP-220 power amp.

Well my thoughts and prayers go out to Mike and his family.

Thanks Mike for everything.

I'm late to the party. I have a Counterpoint amp, originally SA 20 upgraded before I bought it to NP220 and I had this work done by Mike:Upgrade Basic Board to Premium Board, Upgrade remainder of amp to Gold level, Vanden Hul wiring, new Nichicon caps, I had already upgraded the transformer.

Unfortunately I didn't save any further documentation of the upgrades. If anyone can tell me where that might be, I'd appreciate it. Also, I'd be interested in what are replacement tubes. O haven't done any such, but I'm going on 10 years since the last upgrade.

I assume the transformer is a Plitron? Was the choke also changed out to a Plitron choke? I would have to look at the website to see what resistors were replaced. What output caps are in the amp now? Depending on the sound, V-Caps can be added (copper versions) to make the amp have more resolution and a little sweeter depending on the caps in there now. Go to the Alta Vista Audio website and send me an email directly. Peter

I can also add tube regulator to improve bass also.
