#95330 - Voltage doubling.
Responding to: ???'s previous message
One of my earliest projects was powering a very nice 12v car radio in my '63 VW with 6v electrics. That used an old valve car radio inverter transformer with the vibrator replaced by a pair of OC28 'geranium' power transistors. The HT winding was ignored, but a few turns were added for feedback and the voltage doubling bit. It occurs to me that might be a way of adapting an off-the-shelf inverter (the extra turns - not the OC28s). Actually, if there was no requirement for input and output to be inter-connected, you could bridge rectify the two ends of the push-pull transformer primary...
