Thanks for the thoughts - and for that Manhattan delight!

I'm afraid about 3/4 of what you wrote went over my head with a great whooshing sound. I can follow the circuit as I read the accompanying text, but I haven't yet reached the stage where I can explain it to someone else.

I hope they've considered the exploding aspect, as they do make some effort to drive home the safety aspect of the design!

Are any of your box parts suitable for this? I can't see that it's too critical as it's just a step up transformer as far as I can see...not exactly a phono coupling stage!

I'm impressed at the level of ingenuity here. For those of us not trained in electronics, the ability to fashion a useful circuit from scratch is quite awesome.

I've had a look for "FT82-43" and end up with some ferrite rings. Are you proposing I just wrap the wire around that and let it be, without the associated surrounds, pins and cores?
