Tube coil frequency& oil resistance
After doing some sketchy calculations for the resonant frequency of the
secondary
I wanted make and use for a tube-type coil, I came up with around
1.6mhz.
Would this be a feasible, or practical state with a vacuum tube coil?
The tubes I'm going to use are a pair of 5514's, very similar to 811a's,
(in every way except availabilty). I wanted use a conical form i had for
the secondary, and the wire i allready have plenty of: 24 gauge.
At these high of frequencies, I'm going to need a fairly small number of
turns in
my primary, aren't I? To get that lower inductance I'm probably going to
have to increase
the coupling beyond normal limits, which brings me to my second
question:
Would being submersed in mineral oil adversely effect epoxy, plexiglass,
or the magnet wire's coating?
I know there are a huge variety of types of insulation for magnet wire;
for those sages
out there versed in such matters, would knowing that it was a dark,
blackish red
incolor help?
