Subject: [Amps] .01uf caps across diodes ?
What's the consensus on wiring .01uf disc caps across diodes in a HV supply
?
W8JI sez they are required, and used in ameritron amps....and used to
eliminate switching transients.
Some say the caps are required to meet emc specs on commercial gear.
I can't see how anything can get past the HV fitter caps.
KM1H also uses caps across diodes. He also used another method, with a
.01uf cap across an entire series string of diodes, like a .01uf @ 5 kv
type.
Orr's books recommend caps across diodes... to eliminate noise on TX on
ssb. .
Are they required...or not ?
