A bad tube would be my 1st guess. Try this. Looking at the back of the amp, with the amp on standby, pull out the 1st tube on the right. Turn the amp on. Does it feedback? If yes, then put the amp on standby, and pull out the 2nd tube from the right. Turn the amp on. Feedback? If yes, just continue pulling tubes in this manner. If no, replace that bad tube with a known good one. If it feedsback now, then it's probably not a tube problem...Jerry
