EVH 5150 lll Combo Feedback

[ah5150]

Up until only a few weeks ago i hadnt had this issue. I have been getting really static(y) feedback with some popping in between. This is my first tube like this and im not sure what it could be. Its on all 3 channels, and the 2 tubes in the back have a nice orange glow still. Any ideas?

I had a similar issue but the amp was not a tube amp. I thought I figured out the problem was a low battery on one of my effects pedals, but it started to happen again a while later after I replaced the battery. I think maybe it was over heating as it only happened after the amp was on for a while. Anyhow, I never really figured it out and got rid of the amp.
