OT: Open wire feeder cautions

Edward R Cole
Ron relates getting an RF burn.  I recall getting burn thru my finger
from a 432 MHz 5w tripler.  I always attributed it to the 800vdc on
the plate but may actually have been RF.  Poked a pin hole burn right
thru my finger (very painful for a couple weeks).  I was more careful
handling live circuits after that (about 1966).  The tube was a
high-level tripler from 144 to 432 MHz.  I drove an 832 triode with
about 15-20w getting about 25% output on 432.  That made my first
contacts on the band with CW over about 40-miles.  The output tank
circuit used a metal nut can as a coaxial cavity.  Yeah sounds "nutty"!
