In my amp (Peavey XXX), when my EQ (with treble turned up only), chorus, and reverb are on, I get a nasty scratchy, humming, sound that does not go away. I do not have a problem with the EQ, chorus, and reverb when they are on at separate times. Do I have microphonic tubes that need to be replaced?

To check if your tubes are microphonic, just tap on them very lightly with your fingernail.

If you can hear it through the amp, they're microphonic.
If not, you've got other problems.

Actually, you might want to use something nonconductive that isn't a body part, like a pencil. Powertubes will burn you pretty quick, and it's not fun to burn your fingernail.

You should probably listen to this guy 'cause the only tubes I've tapped are the ones on my VJ, and that was within 2 minutes of turning it on.

Thank you. Also, another thing is everything is fine when I turn the reverb to half with everything on.
