First, make sure all filter caps are discharged. Next I would check all
HV rectifier diodes ... then we'll see where we go from there.

Well I was using my Centurion tonight in the CW Open. All was fine until ....BANG!
When I went to test it later, there was no plate voltage. I don't see anything obvious. I
pulled the tubas and still no plate voltage. Testing the secondary of the power transformer showed
50 ohms across the secondary and 1 megohm plus from either end to ground. I haven't tested further.
Anybody have any suggestions?
