    This is a great amp as I'm finding out...but it still is a bit problematic. The volume drops noticeably about 3 minutes into playing, then comes back. Does this a couple of times then it stays as normal...seems like something needs to warm up.

    How should I trouble shoot this? I've used deoxit in the FX loop, master volume knob, and the guitar input jack for starters, but still the same problem.

    Next I do what? Checks the tubes? Anything specific to look for?

    Thanks

    Fresh tubes and a proper bias will probably fix the problem.
