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.

Back to Radio / Amp stuff

Hello all you smart people, I don¡¯t have any
electrical training but I am slowly building 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.
