Hey all,
I have said amp and am wondering if anyone has had the issue mentioned in the subject line. I will be playing (at any volume) and all of a sudden there will be a deafening noise coming from the amp. Not feedback, just a loud, awful, content noise. Any input other than "how old are the tubes?" is much appreciated.
Here's a video of the noise. http://youtu.be/UG9gGuBEOqc
 
it look like a resistor when warm lose propreties and bleed all gain suddently to pre amp output ...

need to take your gear to an amp tech.
