Hi there. I just had one or more brand new el34s short out in my RM100. 2 of the tube fuses blew and I shut it off immediately. Now after replacing the fuses with like fuses and some known good 6l6s I have some problems. The tubes bias up fine, but after the amp gets good and warm a very slighly audible oscillation begins that seems to be in the 400 to 500 hz range. There is also very little volume as I increase the master volume. The amp is audible, but not much louder than speaking voice. Any ideas?
