Default Sima PW-3000 integrated amplifier

I'm wondering if anyone has a schematic for the Sima PW-3000 integrated amplifier (the circuit board reads W-2050R). Failing that, perhaps someone has encountered a similar problem.

The amplifier has a persistent hum/buzz on the speaker lines which does not vary with gain. It is loudest when initially powering on the amplifier, a surge which stabilises after one or two seconds.

Any advice?

Hello

If you can't find a schematic for your amp, you can take a look at this Sima 3050 schematic, it should be close to your amp.

I should add that I did contact Simaudio, and this was their response:

"Unfortunately, diagrams for this product are no longer available. However, we do continue to service it should you wish to send it to us [...]"

Hello

Sima amps was designed by Victor Sima in Canada, and after many years of business he sell his company to Simaudio.

And few years after that, Victor Sima opened another amps company named Linar, but arround a years ago he sell this one to a guy in Ottawa, last time a friend of mine talk to Victor Sima and he told him that high end audio are a difficult business and that's why he sold Linar.

Bye
