Anyone here into fixing stereo amps?
I have a Marantz PM7000 that gets intermittent static through both left and right channels. Normally resolved by a thud to the unit.
Anyone know what the issue is and can I/someone fix it fairly easily? Loose soldering somewhere? dirty connections? I have bought a new amp but would like to give this a go.

It is likely to be a connection on the front ... volume, balance, etc. Some switch cleaner (or pure alcohol) applied to these parts might sort it. Obviously don't do this whilst plugged into the mains, and let it dry (evaporate) before using again.

Great info, thanks.

I should have mentioned that only the left channel had a problem to start with, so I switched to mono and only used the right channel but then the right channel inherited the same problem after a while.
Does that help narrow the problem? :/
