Right in the middle of the CQWW contest my AL-1500 goes bang.
Thinking that I might have lost a tube, I disconnected the anode connector and
turned the amp back on.
After the warm-up period, the HV goes to the normal level, stays that way for
a couple of seconds, then returns to zero.
There are no signs of any charred components.
Any guess what's wrong?
