I ask here because this might apply to a VL 1002 head as well...

My VL 502 has a problem ...
When I when play through the amp without using the FX loop, or with even with using it the sound now fizzels to a shitty low crackly/breaking up type tone , turning the stand by on then off again brings it back to life...only to fizzle again after a few minutes, I am using Ernie Ball speak cables, all new Electro H tubes
do you know what this could be?
also, the amp hums, kinda like the sound when you tap the end of a plugged in guitar jack ...I see the hum adjuster in the back but I can't make out what kind of screw driver it takes...or even how to properly adjust it...sadly none of these things are covered in my manual

it might need the updates that are on the vl1002 repair dvd. lee repaired my 1002 it was very reasonable in price for what was done too it. email lee and he'll give you a better response than i will. best of luck on your amp bro.

I had the same problem. It turned out to be an open resister on the underside of one of the power tube sockets.
