My gold top jack casady recently died. No output at all. I checked everything I know to check and couldn’t figure out the exact problem. My tech now has it and he said the transformer/inductor, whatever it is, has signal going in, but none coming out. It’s fully epoxied, so he can’t do anything with it. My problem is, I cannot find parts ANYWHERE for a Jack casady. There is no part number, model name, nothing marked on this transformer. Can anyone help?
