I've got a Peavey Triple XXX and when I turn it on there is some sort of hiss that sort of fades out. I'm hoping it isn't a grounding issue or something like that. I've been swapping out pre-amp tubes and nothing makes it go away. Any ideas?

When you say you have been swapping out preamp tubes, what exactly have you been swapping and how?
Gear:
Fender AVRI '62 Jazzmaster, Fender Gold Sparkle Strat (custom), Custom Swirled Roswell Rhoads
Marshall DSL15H, Weber Speakers, Fender Champs (x2),
'63 Fender Reverb, Mosrite Fuzzrite, Joe Bonamassa Fuzz Face, Whiteface RAT

^ it means he is swapping his existing preamp tubes around in order of position

V1 -> V2
V2 -> V3
V3 -> V1

as an example.


ticklemeTS - did you try a different power outlet or house maybe?

if there is still hissing after the swapping you could still have a microphonic tube.

do the pencil test or go ahead and get a preamp tube in there to test with.
