Sure let me see if replacing electrolytic caps helps…sadly do not have an oscilloscope! Let me see what I can do to with a multimeter 😅

Were you able fix this? Bought an MT 70 which didn’t turn on to begin I opened it to see that it was missing the 2sd313 series pass transistor and replaced it with a tip41c and viola it turned on till it didn’t!!! It powers on in the sense that the power led glows and nothing else seems to happen…any help on how to go about figuring out what’s wrong and how do fix it will be helpful I’ve cleaned up the board with some wd40 so far
