AFAIK Tony the only units with a direct battery HT were the Zamboni piles used in hand held devices like Type K. With virtually no current drain as the tubes were cold cathodes, each cell of the battery was a thin coated disc about the diameter of a 2p piece. Vehicle based power units were a vibrator giving awful square waves into an ignition coil to get the HT. In fact one system tried was powered by the ignition system of the vehicle - not very successful!
My Tabby Type E is now powered by a little transistor inverter around a small toroid I found in TV set & a Cockcroft-Walton multiplier to get the required HT. Very little battery drain now & very portable.
I am trying to find oit if any of the original Zamboni piles that were used in the IR devices is still operational. Has anyone ever heard of a unit that still works with the original Zamboni pile?
I am trying to remake one and was curious is the fabled Zamboni lifespan (over 100 years) had been achieved by the copies that the British made in the 40's

So has anyone ever heard of one that still works?
Thank You,
