Did anyone notice the article in November 2003 QST about the guys modifying
a Collins 300-G (AM BC band ) to HF. They attached motor drive controls
for the plate tanks circuit but no mention of the neutralization circuit.
It has two triodes in parallel with PI-L output and inductive
neutralization from grid to plate. This type of transmitter was intended
for fixed frequency operation. I tried to email the author but it bounced.
