Default Counterpoint SA 5.1 repairs

Hi,
I have a Counterpoint SA 5.1 pre-amp that had a power supply tube arcing and had the amp repaired by a local (so called) tech... The power supply caps were replaced (2 caps replaced with 4 smaller ones) and once i got it home it worked for about an hour and a couple resisters fried and other tubes arcing (power supply tubes in the main chassis).

I love this amp and I really need someone competent to repair and tune it up.... Does anyone know of a good tech in the Toronto, Ontario area that would do a great job?? I would really appreciate any info. I'm willing to invest in this amp. It is in otherwise original condition, most tubes fairly new.

Thanks,
Andrew

Hi Andrew,
This is an old post, so I'll through this out for you. I used to run the Canadian factory service shop, and I still do service on these. I had stopped servicing a while back, but after I have my new bench set up I can help you. The entire Counterpoint story is a very sad affair. Michael couldn't design a power supply if his life depended on it. Your failure isn't something that failed. Your failure was designed in many years ago.

The PCB under the tube has to be cleaned of all burned material and filled with epoxy. Traces are cut and wires routed to the pins. The root of the problem is too high a supply voltage and too small a separation between those two points.

The main reason I am replying to you is that you haven't had any replies to your post. I hope you got it sorted, but in case you haven't and you still have the preamp ...

-Chris

Hi Anatech..
Thanks for responding. I still have the amp and it still needs the repairs. I'm glad to hear you have your bench set up again and I would appreciate you having a look at it. Let me know how I can reach you. Andrew

Anatech,

I too have a Counterpoint 5.1 Preamp that needs some help - can you service this if I can send it to you as I am located in N.W. Ohio?
