I bot 100 of the GE 42L3332 snubbers from Hosfelt. These are the 0.33 uf -at- 2kV DC The AC rating is 750 V RMS. I stuffed two pieces of perf board with 15 caps each with a 10 meg resistor across each cap. I have the two boards of 0.022 uF -at- 30 kV DC each which I can connect in series/ parallel combos. The polypropylene caps run fine and remain cool to the touch. Cheers, Ralph Zekelman
