I put in the new vibrator and now I have a hum that I can control with the volume knob. I will have to check my solder joints and look at some voltages tonight. If it was 1968 I would take the tubes to the local Totsum store and check them. I guess I can bring home the scope and see what I have going on if the Simpson and some voltage checks don't clue me in. At least now I have an output to play with.
