[QUOTE="JKMV12, post: 109106, member: 2019"] so then i guess the screen resistors are likely the cause of the issue. the streaks on the top are about 1mm long and in random orientations. there is one streak running along one of the short edges. i don't see anything else black or damaged around the resistor. was it probably arcing around itself? if this is true then by arcing/shorting across itself the effective resistance would be lower. this means that the voltage at the screen would be somewhat higher which would push the closer to maximum plate dissipation. is this hypothesis plausible? i'm just trying to understand how it caused the problem. of course i am going to take this to a professional. i know someone at the university who might be able to help and if not i know of a local tech who should be able to fix it. I appreciate all the help and advice that you guys provided. hopefully i can get the amp to the tech sometime this week and then we can call this case closed. [/QUOTE]
