David,
thanks for the comments. Sometimes these sorts of posts result in a deafening silence and you wonder why you bothered!
I think I used MS Visio (which I had an old copy of) for the circuit diagram. Then pasted into Word.
Absolutely any old enhancement-mode N-channel MOSFET will do - They just need a decent voltage rating.
I certainly didn't pay more than £1 for mine.
FWIW the main switch was a 3-position toggle/lever switch, one position spring-biased. That means that you can flip the switch briefly to the "discharge" position, make sure the discharge LED goes out then release and you are ready to go again. I regularly do this during reforming sessions, even if the cap looks good.
