MOT power supply webpage created



Original poster: "Andy Cobaugh by way of Terry Fritz <twftesla-at-qwest-dot-net>" <kb3ewy-at-rcn-dot-com>

I have been talking with Tim Johnson, who did the original 4 pack, 6 pack,
and 8 pack MOT power supplies.  I have just uploaded a new page on my
website describing these power supplies.

http://users.rcn-dot-com/tcobaugh/motpsu.htm

I did this to try and get all the information about these beasts together in
one place.  It still needs some work.  If anyone has tried these power
supplies and would like to share your results please do.  If you have any
suggestions for the page, or possible errors, please let me know.  If you
even have pictures from your experiments and have them on a website of your
own, I will put a link to your site on the page, and if you don't have a
site, you can e-mail them direct to me at kb3ewy-at-rcn-dot-com and I will put them
on my site.

I think we really need to push the MOT power supply because it is so cheap
to build, and yet as powerful as pole transformers, lighter than pigs, and a
lot stronger than NSTs when put into Tesla coil service.

On a side note, I will soon have a chance to fire my 4" coil with a vortex
gap (soon to be triggered vortex gap), 15/60 NST, and 25nF tank cap.  I will
post results of this.  Should it be run with a tank cap so close to 120BPS
LTR?  I am afraid that the gap will miss a firing and kill the transformer.
It is set at less than 1/4" to help prevent this, and safety gaps are at a
hair less than 1/4".  Is it normal to have a very narrow range of tuning
with a cap this size?  I couldn't seem to get it in tune last time I ran it.

Cheers,

Andy C.
