My friend gave me a peavey supreme head that didn't work, so i offered to take it hoping it would be something really easy that i could fix. i plugged it in to an outlet hit the switch, nothing, the led "indicator" didn't turn on. so i opened it up, checked the fuse, good, checked for any frayed wires, nope, checked for any burned or suspicious looking components and circuit board, also good. i haven't gone any further because i don't know if i want to dedicate my time. i would like to test the transformer but i don't know how. i have a good feeling it is a power supply problem, i was wondering if any anyone has ever had this problem or if anyone knows any test points that i could measure with my multimeter ?
