Hi All,

Reinhard wondered about the drain resistors I use being overloaded.

I use YAGEO Carbon Film CR-50  1/2 watt 5% 10m Ohm resistors (Digi-Key
10MH-ND  $12.87/1000 ).

I wired one across one of my 56nF 1600 volt caps and ran the voltage up.
At around 4000 volts it started to turn brown and smoke a little (~2
watts).  At 5300 volts, it gave a very nice CRACK!! and arced along its
outside surface!  It now measures as 11.1 Mohm.  I think they are pretty
good but obviously underrated :-))
