[Amps] AL-82 Blowing fuses on startup

[Dave Cole]

Hi,

Interestingly enough, I just asked the Ameritron people the exact same
question...  

My amp has done this a few times as well...  The support folks
indicated that the Step Start Relay may be sticking...  I have not
looked at mine yet, as the amp seemed to stop this sort of action a few
days ago...
