Yup, we're WAAAAAAAAAAAAAAAAAAAAY off topic, but I was first licensed in
1977 as WA6ZGB, eventually changing to K6JQ in 1996 (first day of
the modern vanity callsign program). I don't have one of them fancy
island DX callsigns, though.
Bleeder resistors are quite important; when I fixed out microwave oven
(replaced the magentron), I was pleased to see the filter capacitor comes
with an integral 10M bleeder :-)
As a slight effort at getting us on-track - is pure-silver the Morse Code
of Photography?
Cheers (and 73 to the hams),

DEAR FELLOW HAMS,
I started as WN2EYC in 1962, WB2UYM, 2 years later and for the last
17 years have been AA2CV but I am 8P6FF where I live.
I also built a linear as a 15 year old. I used a 1000V plate
transformer and a voltage doubler with some very large oil filled smoothing
capacitors. I recall my mentor, John, WB2IHB handing me a very large high
resistance, high wattage resistor telling me that using it as a bleeder from
the capacitors to ground would save my life at least once. He was right!
He also gave me a pair of radar amplifier tubes (I have them in
storage but forget the #) to use in grounded grid parallel as the final
giving me a kw. Yes their plates glowed when keyed but my favorite was
taping a neon bulb on a plastic stick and holding it 4 feet from the finals.
It glowed when I keyed the Xmitter! Impressed friends and family. Needless
to say, I kept a metal cover over THAT baby and grounded everything VERY
well.
Waaaaaaaaaaaaaaaaaaaaay off topic.
CHEERS!
BOB 8P6FF
