Hi all,

I have a Marshall Lead 100 Head Model 3210

The amp cranks just fine, but after 10 minutes or so, I lose total volume, not power.

If I turn off the amp and then turn the amp back on, or if I increase the volume to max and play, sometimes, I get all my volume back.
I have already changed the following parts without success!:

All Potentiometers
All Jack plugs
All Power capacitors
All Transistors
All ic`s (op-amps etc)
and checked it out for any dry joint possible!

Any idea what that is or why this amp does this?

Thanks and any suggestions would be appreciated.
