"Enhanced" Drain Resistors :-))
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 :-))
