<DIV>Thanks for the info George. I found some HV diodes on Amazon for
tesla coils. They appear to operate fine so far, I am running tests right
now. You are correct, I was worried about the faster switching rates for
CRT use vs microwave diodes.</DIV>

hopefully you’ve probably solved your CRT hv diode problem, but here’s a vendor
with (cheap) fast switching HV diodes:

<DIV> </DIV>
<DIV>At 15kHz pulse rate from a flyback, diodes made for 60hz, like transformer
type microwave oven diodes, are generally too slow a recovery time, and overheat
above several kHz. </DIV>
