Amp noise

[schofnsteen]

I hear a crackling noise after turning amp on with NO Chord plugged in. After I plug in it is not as obvious but do notice a change in volume while playing as well. Is it the tubes? Which ones? Anybody know?

I need more specific info... It can be many different things.

Agreed. Dirty tube sockets, or pins, come to mind first.

What amp? Do any of the controls affect the volume? Need more information.

Mine does this too and it goes away after about a minute or so.

It does go away after about a minute but I have had the Marshall Jubilee for 18 mos and this just started.
