"You state that you "get strong IF oscillations from antenna to speaker". Do you mean that you injected a 450KHz signal with 400Hz modulation from a signal generator?" Yes.
"Does the oscillator section of the tuning cap have the same amount / size of plates as the RF section?" Yes. They are identical.
"You state that when measuring the grid voltage, the oscillator shuts down. Do you mean G1, the Osc grid on the 6A8, Pin 5". Yes, the oscillator grid.
The only difference I can see between my schematic and Terry's, is he eliminated 17b, a .02 mfd cap.
