I hear it, untill I lightly tap one of the powertubes, then it stops. What's wrong? (The amp is 7 years old, but has been never been used until I bought it a week ago.)
Thanks
EDIT: This doesn't happen RIGHT when I turn the amp on. I would have to have been playing for a while first.
It's got 6L6s, to put EL34s in there, I just swap them and turn the bias switch to EL34? Which Groove Tubes Rating should get for the amp?
