Noisy Carver PM1.5...

proffsound · 26th May 2006, 03:15 AM

Hi everyone, I have a Carver PM1.5 (being used at 220V) that´s been stored for a while. I´ve tried it out recently and it sends out some noise that comes from the Triac (as far as i´ve been able to trace the source).

I Would be needing the datasheet or the circuit array in order to measure voltage and take a look at the components.

If any of you has an idea of which may be the cause of the noise, or knows where I may be able to find the circuit squematics.

I would be really thankful.

That´s all, thanks for reading.

Is the noise an uneven ticking?
How familiar are you with amplifiers?
Do you have a rough idea on how a Carver works?

The high supplies normally run bipolar 120~125 VDC. Be careful. The caps stay charged after turning off.
