Hi Chris I was about to say that these things are usually a push-pull self
excited oscillator...but this looks like a much more modern job. I didnt
realise plasma etching was done at so low a frequency..... the ashers we had
were on the 13MHz ICS band. 3kW 120v transformers are no problem they are
used on building sites for power tools. I think the firm's name on the front
looks like "Plasmatronics" (maybe ix instead of ics) and I think they have a
web site. These should be mildly bomb-proof as they are made to operate into
weird loads, by people who dont understand "matching" and it is tweak for
maximum smoke ....literally. That didnt stop some of our crowd trashing a
few valves.( yup ours were "real radio" with big bottles)
Well it would make a difference from Decca Nav PAs !!

Cheers de Alan G3NYK
