Counterpoint SA-7 Schematic

PeterBGood · 24th July 2004, 06:24 PM

I have a friend that is looking for a schematic for the Counterpoint SA-7 preamp. He has a unit that is in parts and he wants to upgrade it. Any help on this?

Hi,

Unfortunately I have copies of some other Counterpoint preamp schematics but not the SA-7.

If no one can help you out you could always ask Michael Elliot.
He's the brain behind the Counterpoint gear and is still supporting most of what was previously produced:

ALTAVISTAAUDIO

Cheers,

Thanks for the Alta Vista Audio link. I wondered what happened to Counterpoint. Their products seemed to me well built, with decent execution etc. Then they vanished. Could it be but, ah, yes, their bank, of course, got nervous, and pulled the plug.

Mr. Elliiot is a very nice and unselfish man.

I hope that his Alta Vista entrerprise is going swimmingly.

ps - i'm pretty sure that you can purchase the schematic from him.

Oh yes, those were fine products indeed.
My first commercial preamp was a SA-5. Michael Elliot was one of the first to use automatic bias in preamps, gridleak bias on the less expensive models as well.

If ever any of you come across a dirt cheap second hand SA-11 preamp, give me a ring....

My own top of the line preamp was inspired by that model but I didn't quite dare to push it that far though.

Cheers,

At $75+shipping, the manuals are a bit steep. BTW anyone got a schematic for the SA-3000 TIA.

Oh, my, I remember wanting an SA-11 many years ago as a graduate student, but my budget allowed only for a used c-j PV-5. Mr. Elliot certainly was ahead of his time.

A bit of an understatement. I wonder why this site is so popular - the upgrades and all services seem to offer dismal value for money.

Send me a PM for the SA7 circuit. I once used to have it and still keep a reasonably detailed circuit (took me no more than an hour of staring at the board to draw it). No PSU as it looked like a textbook emitter follower.

Gentlemen.... The price may seem a little high but when you stop to consider the time and energy involved in designing/building the units its a bargan in my humble opinion. You could always get out Mr. Longhand and draw the darn thing yourself.
