Had some problems with my KEL84. One of the EL84s went cherry when I swapped them and melted one of the resistors before I could turn it off. Anyways, small fix.
But I was wondering if there was any mods I could do to it at the same time. I've almost decided to replace the coupling caps to Jensen PIO and do the approved DC heater supply mod.
Was wondering if there's any merit in changing the resistors? Kiwanes? Tantalums?
