Still having trouble with voltage drop when tuning my Swan 700CX.. At
the power supply the high voltage is well over the 800 V specified, but
when I switch to TUNE. The voltage rapidly drops to less than 400 V.
The output on cw is only about 50 watts and less than that on SSB. What
can I check with a voltmeter and where do I check? What parts might be
involved. I have tried 2 different power supplies with the same result
