Hi All,

I tested the SISG gap and coil out tonight at 116 watts and it works 
fine ;-))  Firing voltage was 3600V   150nF   120BPS  105kHz...

Here are the new boards all mounted up pretty:

Here are the MOTs.  Didn't have time yet to mount them up nice:

6000V  150nF MMC:

Here it is arcing nicely to a point 15 inches away.  It could have 
gone further:

Here is a little 14Meg movie I put on rapidshare.de:

Go to the bottom and click "free",  Wait about a minute for the 
countdown timer, type the funny letters in the box and download 
it.  You don't have to log on or pay anything.

I ran into a charging loop problem so I stopped for the night (tired 
:-p).  But the SISG gap is working perfectly!!!  The heat sinks 
barely get warm.  I never used any ballasting.

Cheers,

        Terry
