RE: Full wave bridge into Choke PS

"I parallel every diode with a 0.01u disc cap and 470K resistor (values not critical)."

A very reasonable action, when most PN junction diodes are employed. FREDs can exhibit "funny" behavior, when snubbed. Snubbing diodes is unnecessary, when they are Schottkys.

The single snubber I mentioned is specifically for choke I/P filters associated with SS diodes. Without the cap. or MOV, inductive kick back spikes can destroy SS diodes. The situation is 1 where the electrical fragility of SS is illustrated.

Tubes are mechanically fragile and electrically robust. SS parts are mechanically robust and electrically fragile.
