Dear: cam wa4jrw,
i have an amp (ampsupply lk-500) that was blowing the caps and the string of
diodes, at start up. just the same problem you have, the inrush current was
too much at times for the caps. and at almost 10 dollars each they are not
cheap if i have to replace them 2 to 3 times a year. i resolve my problem
with a big heavy duty variac bringing the voltage slowly to 4000 volts max. i
had no problem ever since also is this is your case ameritron sells an
external in rush current protector about $80 give or take. older amps don't
have the inrush current protection like the newer ones. maybe somebody else
might have a better idea. good luck. Pete WO2E.
