Default Design help: Modulator schematic

As others in the other group have mentioned, you're pushing your luck with
600V diodes. They have over 700V on them (or they would have if things were
working right). Replace them with 1000V diodes. This also means you need
to replace those capacitors with 1000V capacitors, preferably AC rated.

As someone else said, you have a major problem with the power supply. The
output voltage should be much higher.

To get my real email address, replace wrongname with eportiz. Then replace
nospam with sacbeemail.

Reference "Design Help" thread in rar+p

Thanks for any advice you may have.


Just noticed I forgot to draw in the caps across the diodes in the
schematic. There is a .047/630V cap across each diode.
