I sent this once before but I never saw it show up, sorry if it's a dupe.
I have been looking at the June 2006 QST article "Homebrew Solid-state 600 W
HF Amplifier". I'm gathering the parts for the power supply but have a
question concerning the bleeder resistors. The author, K0GKD, used four
22ohm 75W resistors he had in his "junk box" in a series/parallel
configuration.
In addition to providing a discharge path to ground for the caps, the
bleeder resistor provides a measure of voltage regulation as well and this
is where my question comes from. What would be the optimum value for the
resistors? I've searched the net and various handbooks but haven't found an
answer.
I have (4) 35000uF 80V caps available for the supply.
Thanks for you input.
Bob
