The Drake AGC circuit is very high impedance: on the order of

*** This high impedance stuff can be confusing. My KWM-2 had a thing where
it would take a second or two to switch from transmit to receive. Turned out
to be a leaky capacitor in the very high impedance T/R circuit. The leaky-ness
was so small that the cap looked just fine on all my capacitor testers, including
an old Heathkit. I have since acquired a Sprague TO-6, and I think that one might have
found it.
