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.

There are a few people doing repairs and modifications. I am in New Jersey so if that is convenient for you let me know, if not let me know. Don't post here, send me a message through Audiogon messaging.

Dear friends, I have a pre-amplifier Counterpoint SA-5000, I got it in 1993 and it has been damaged once, it repaired in a technical workshop but they took 3 valves and put new circuits. After the repair the sound of the preamplifier is no longer the same. I know a Audio technical service that would rebuild it, but I can not find the electronic schematics. You know where I could find them?

I have the schematics and I have serviced no less than 5 of them.
Most of them have failures like popping caps, rustling plate resistors, blown rectifier 6CA4 and blown Zeners.
Why would anyone take out 3 valves?  I assume they are the 12AX7 error amp and the 6922 pass element in the regulator section.
If thats the case then the preamp is no longer B+ regulated and you might as well use a Chinese preamp.
The SA-5000, unlike the 3000 and 2000, is a bit tough to service due to the floating chassis and the rather delicate regulator section.
Good luck finding someone to rebuild it.  IMO you might want to find a used unit on Ebay rather than trying to rebuild a butchered unit.
