1A at 60VDC is too much.
Anyway, do what Terry said, and before putting the 80 back measure in the 80's socket between either of the filament (fat) pins and the chassis. You should see large resistance, certainly no less than tens of kOhms. In other words, we are looking for the load short. Then proceed replacing the 80 tube.
