Grid-leak_detector abstract "A grid-leak detector is a thermionic valve (UK, Australia, NZ etc.), or vacuum tube (USA), circuit used in older vacuum tube AM radio receivers, which served as a combination amplifier and detector (rectifier) to extract the audio signal from the modulated radio frequency signal. The tube used a grid leak circuit to generate the DC grid bias voltage necessary for proper operation from grid current that occurs in all vacuum tubes due to electrons attracted to the grid during the positive part of the RF cycle.".

Grid-leak_detector reason "needs the coupling capacitor to leak charge; there's no DC current to provide grid bias.".
Grid-leak_detector reason "these connections not required; may use same config as above or connect RC to grid".
Grid-leak_detector reason "yes, tube's IV curve is typically nonlinear, but that's not the fundamental trick; transconductance could be linear and it would still work; grid bias is changing; small tau compared to grid leak".
