So I was having an electrical ground loop noise issue that I thought was a tube in my F30 going bad cause I have had the same tubes for the last five years. I bought new tubes and replaced both. I realized that the ground loop was caused by my boomerang phrase sampler until I put it through the effect loop in the F30 (problem solved right). The next rehearsal I warmed the tubes for a few minutes and started to play. After about 30 seconds I started to smell burning and I looked in the back of the amp at the tubes and the power tube on the right was glowing red hot. Is this just a bad Power tube that bought or is this a sign of something else?
