This is a really strange problem. The 10UF E.L Cap continues to get VERY HOT (cannot touch it hot) at power on and eventually blows. It takes about 15 seconds to blow, even with a new 80Rectifier tube. Since the symptom is blowing E.L. Cap and no Audio output, I am going to start poking around the 42Tube(Output). My challenge with checking voltages is I do not know what they should be at the plate for the 77's and 42.
