Suddenly I'm getting a static sound from by beloved 12-year-old Carver power amplifier. I've checked it with two different preamps and two different speakers, same sound regardless. I've also tried different electrical outlets, so everything has been eliminatedexcept the power amp.

The music is still coming through but there is static as well.

Any guesses what it might be?

What about without any preamp?

Bought any new equipment recently? (On other house circuits)

Clean the contacts. I've got 10+ year old denon (PMA 720, I think) that has a click dial the switches between tape deck A and B. I have to wiggle it and fudge it to get rid of static and get a clean sound. Frustrates me every time. I'm just lazy to not get it cleaned. That, and I'd be out of music for however long it takes to service the amp. Perish the thought.

I am assuming, of course, that there are hard wire dial contacts that you select on your amplifier instead of merely pushing a button. If it's a push-the-button type thing, then I have no clue.

Maybe this helped?

Is it worse while moving the volume control ?

This is a straight power amp - not a pre-amp or tuner. There is no volume or knobs. The signal goes in, gets boosted to a reasonable level and routed to the speakers.

The feedback is from every speaker post, so it is internal.

Here is photo of the same type of amp (This is not my Amp)

Are you handy with a soldering iron? It could be one (or two) of the two large black filter capacitors seen here:


It would probably cost you about $10-15 to replace those yourself, but I'm not even sure that would fix it.

Just post your same question with a picture and you'll get some good responses I bet.
