Shaun -

It's not exactly clear what the configuration of your MMC is, or what type 
of spark gap you are using. A single string of the .15uF CDE 942 capacitors 
is not adequate for a system powered by a 60ma NST. Your target value for a 
12/60 static-gap system is around .018-.02 uF, achieved with 2 strings of 15 
or 16 caps each.

Here are some pictures of my new NST filter.  I ordered parts from digikey 
this time and used the correct values and MOVs( before I was using 3Kohm 
resistors and door knob caps).  It's built so that I can change from 7 MOVs 
per side to 8.  After reading posts on this list, I think I'm going to use 
all 8 for my 12Kv, 60mA NST because it puts out more that 12Kv at 120V in 
and I'm using a variac.  I'm using 50 watt resistors for the 1Kohms, I can't 
get ahold of the 100w versions, does anyone on the list have some for sale?

Question:
My capacitor bank is currently on 2 boards and I'm going to make a 3rd board 
of CD 942 caps (14 caps 0.15uf in series spaced).  What are other coilers 
using for board to board spacers?, I want to stack them one on top of the 
other, and legs to keep them off of the floor,  right now I'm using 1/4 inch 
nylon bolts with heat shrink tubing over them to strengthen them.

thanks,

Shaun Epp
