Yesterday, I turned my L4B on and the tubes lit up and the blower ran and the plate voltage was up to par.
Today, I turned the L4B on and I heard a loud buzz/grunt. The breakers did not trip in the power supply. I turned the AMP off and scratched my head. I suspect the filter caps in the HV power supply. There was no HV showing on the meter . I left the power supply on for only 2 or 3 seconds. I have 8 new caps to replace the old ones with, but I just had surgery yesterday and can't get up enough steam to check it out. I am wondering if any of you have witnessed the way your power supply acted when the capacitors shorted? Your experience? Thanks and 73, John, K5PGW
