Dear Rich,
Look at your reflector archives for the past couple of days.
There¡¯s a ham who is selling all sorts of amplifier parts,
including plate chokes.
W2CQM, Ron Lumachi.
He¡¯s been on the reflector forever, and he has some great stuff.

Subject: [ham_amplifiers] Enough- Now to a Choke
Back to Radio / Amp stuff
Hello all you smart people, I don¡¯t have any electrical training
but I am slowlybuilding an amp from my junk box. The power supply
is complete. I enjoyed the information about ¡°glitch¡± protection
and did a cut and paste of all the important notes, making my
information list to build by. I will use a 50ohm resistor and a
small gage wire as a fuse in the HV line. I will also put in a fuse
c/t of the filament / bias line. I don¡¯t have much money (retired)
to buy but a lot of stuff to build with. My next thing to figure
out is the plate choke for a 4-1000A, I plan on about 3500v, first
test, it nothing goes up in smoke I can later up the voltage to
4500. The amp will be a mono-bander at first, 21Mhz. With out a dip
meter is there a simple way to build a HV plate choke. I will not load it to the max , just trying to make something work.
