"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.
