Hi Jetijs,

I actually thought that it wasn't that much output from seeing the magnet move like that but compare to what was dumped, I think it was a good result. The biggest cap dump I did was 1000v @ 66uf?? maybe maybe not. It was 5 caps in series..each was 200v and 330uf...those photoflash caps you see in the last pic in series in the vid.

I haven't tried a step down and don't know much about that one on ebay. I think I don't recall exactly the diodes but it had to have been one of the three:

1n4001 (string)

one to three of those microwave diodes

or a string of the 1a100's??? 1000v 6a diodes? I posted that in the water spark plug thread somewhere. These were VERY inexpensive and a string to make 15kv for example was a FRACTION of what the larger diodes were for the same rating...but I do like the idea of 1 single instant shutoff and not a series of diodes.

If I had the parts or knew a good one to use, I would use a vacuum triode and use it as a diode because that is what Gray did...but Gray apparently drew his triode backwards to confuse people possibly or maybe he goofed. Bedini always had it correct in his drawings.
