[QUOTE="kc2eeb, post: 110562, member: 811"] It's not the tubes, it's the board itself. Please look at these pictures I took of my amp while I was repairing it. http://mtsforum.grailtone.com/viewtopic.php?t=12785&highlight=lots+pictures+rm50+repair The problem was the board itself arched HV to ground. It was an intermittent problem until it finally shorted enough to leave evidence of a short. I had tried different power tubes, checked and replaced the screen resistors, and finally the OT and power amp circuit board. [/QUOTE]
