Not a great idea to run to set with just the 80 tube in it. Without the other tubes in it the power supply is running with small load on it. This can cause voltage at the filter caps to soar very high and short the input cap. Same thing can happen by running the set without the speaker plugged in.

Thanks for that tip Terry, I had always though it was ok to run just the 80. I will remember that and not do that again..
