AVC with Russian Rod Pentodes

[Mike Watterson]

I was planning just on using a DC amp on a diode detector to drive g2. The manual "RF gain" control on one of my Hallicrafter sets is simply a pot varying HT on an IF 1T4 g2! It may vary g2 on other 1T4s. I decided that though the Russians used the 1j37b for AGC that it was rather heavy on filament current.

Your approach sounds interesting Kalee
