Problem with B-52 ST-100 Head

[chris-o-fer]

Hey guys. I've had my B-52 ST-100A (all tube) for about 2 years now, and lately I've been getting this massive 'crackling' sound out of my cab. If I smack the top left corner it stops. (wtf) I'm guessing it's a loose connection or something, but has anybody experienced this problem with this amp or, another head?

crackling? cou7ld be your tubes going. or a loose connection or dry solder joint. In any case, if it's the valves or anything else I'd advise taking it in for a repair before the problem ends up doing something really nasty (like a short, or just total death)

A good amp tech should be able to sort you out
