Explosions and vapourised tools are part of techy black humour, we always compare and laugh at our biggest cock-ups

The pain we have to go through to give you things that are safe

Colin said - "Class D with saturable magnetics output stage i.e. a magamp design normally used in big S.M.P.S.U. This will mean the output device are just made from wire and not semiconductors thus basically bomb proof, fun eh."

Last seriously used in the German V2 rockets aimed at London?

Blimey you do like playing with odd bollocks . Much easier to create a high current low voltage signal source and use a transformer on its own to exchange the current for voltage, you don't even need to power that, the classic passive bit or wire with voltage gain as in Peter Walkers wet dreams.

More I didn't know about it, it seems others have been at it as well.

I have started comments lads, and ignore the smoke:-

As far as I know, John Harrison tried various solutions to get a pendulum regulated clock working reliably at sea through his H1, H2 and H3 clocks only to be convinced (and win the Longitude prize) by the spring balance regulator which was the basis of H4. So to my mind, Harrison solved his problem by coming at it from a completely new angle.

Apologies, Harrison is a bit of a hero of mine.

Nice interview from two nice men.

Have you seen the movie, bloody good loved it, he became a hero with me to, like Tesla

Gain in a wire yep cone shape core maybe? The magamp I used in a PSU were for a missile also just a bit bigger and RAD HARD nice kits. Shame we set them to go bang after the hard work we did to get them right.
Cone shape core maybe good idea for a cable company DOC mmmm NO

Not forgetting of course the fabled H5 , found in a garage in Peckham some years back

Not the Movie, but read the book and watched various documentaries/drama documentaries on TV. Looks like I'll have to get the Movie!
