George's diagram is looking good...just the reaction to sort out and I am not so sure about the 50K for cathode bias on V1.

The AL1 modification just needs to be changed by removing the 2x 700 and the electrolytic and wiring direct to chassis. The bias will need to be checked once the set is running as we don't know the HT voltage, the 500 ohms can be adjusted to suit.

What we do need is some better pictures around V1 and the volume/reaction control so that last bit of the circuit can be finished.
