The approximate values are, SB-200: 200 ohms; 3-500Zs (pair): 54 ohms. These
are from memory cells, others can tweat them for you.

Howdy All,
KK5YY Jerry the new guy here with a question. I have read of a technique
for tuning the inputs of Pi input amps that involves removing the tubes
and
replacing them with a non inductive resistor then tuning with an antenna
analyzer.
My question is what are the values needed for 572Bs and/or 3-500Zs.
A local ham bought a basket case SB-200 from a silent key and I am
trying to help him he it back together. I have a LK-500NT that I would
like to tweak up a bit so any information would be greatly appreciated.
Thanks for any help 73 de Jerry
