I have a tube radio that I replace the caps in, now when you turn the radio on from cold the 6aq5 tube wil arc snap, and loose it's vacume, I cant figure out why it would do this... Anyone have any ideas?

First, I'm going to assume you replaced ripple filter (power supply cap).

Did you replace it with the same value cap, and did you install it with the polarity correct?
