Hi Al, as said, I can't really find a decent description either, I believe the Jones supergainer circuit was changed later to grid leak as opposed to cathode bias, the coil arrangements were the same though. The tuned anode tuned grid is the only one I have seen as well where there is no mutual inductance involved.
Regarding the supergainer circuit, if the bottom end of the capacitor across the sec. of the IF transformer was connected to deck then the circuit would make some sought of sense.
