Default Re: Bach with sparks!

Hey Albert,

Re MOT’s: they are actually quite heavy, as you know, and they’re also really inefficient unless they’re seeing the right impedance load, which is a magnetron with doubler circuit.

I have a lot of experience with them and they served me well for years , but I ended up wanting to improve efficiency, so after an approach from me, Ed designed and wound one on suitable lams. It was /is fit for bigger start-up currents as I stepped away from the small, oil-filled caps from scrapped microwave ovens and towards larger ones. As Ed drily noted, it would make a good electric chair.

It’s a moot point now as even two MOT’s would be an unwieldy and unwise lift from floor level now.

I’m glad you fixed the arc and am looking forward to seeing your progress.

Take care!
