I just fired up my amp after a jam yesterday, and Im now getting a periodic thump coming from the speakers. It starts every 5 seconds or so, then after a few minutes of playing becomes more of a pulse like a bass drum. I thought it was maybe power as I was using a plug I never used but that wasn't it.
I turned off my lights to check the tubes and noticed a bit of a blue arc in one of the power tubes when it thumps.
Do you guys think its just the tube? I have to do some digging to see if I still have some spares.
