Hi Rob,

Wow! Kudos to GarySP for finding sources for 2V Batteries and a solid state vibrator that can run from 2V.


Take away all the power supply stuff from this radio and you have a radio that runs on a 1.5V "A" Battery and a 90V B Battery. You could run this thing on a 1.5V D Cell and ten 9V Xistor batteries. This will at least allow you to test the radio before attempting to repair this power supply.

To try to run this radio on 1.5V and 90V batteries, do the following:

Leave the power switch in the off position.
Connect A and B Battery negative terminals to chassis ground.
Connect the A battery + terminal to the tube side of R11, R12, and R13.
Connect the B battery + to the "Circuit" side of R10 (The side that connects to the Audio transformer, B+ to other tubes and the "B" tab of C21.

If the radio works, then U can spend the Bux on the 2V cells and the vibrator.

Good luck!!
