It looks like the time is coming for me to get it out and draw up the circuit.
It uses 6.3 volt valves and once had a lead acid battery driving the heaters directly. The inverter was also powered by the same battery.
There will be a delay though as my scope has packed up and either needs looking at or another duff one will have to have a PDA transformer rewind.
