Unless you've misplaced a decimal point, your cap is too large for your
NST by a factor of ten.  I've not checked the pri-sec resonance.

Hi there list.

'Nother First Light post. :-)

these just something not quite right, however..
here's the new coil specs..

9kV/30mA Franceformer NST (just untill its tuned, then I switch to a 
12kV/60mA)
Single gap SG, with a 12v muffin type fan.  Steel contacts.  Itll be
used 
untill I find the time to finish the RSG i've got sitting on the garage 
floor.
Geek-Group type SW bucket cap -at- roughly 0.119uF.
(or a 0.133uF MMC w/ the 12kV NST)
13 turn primary with 0.25 Copper Tubing, 0.25 inch spacing on 6 PVC 
supports.
1036 turn secondary, 8.1" by 28" form, 22awg magnet wire, 11 coats of
Behr 
"spar varnish" type polyurethane.
Doughnut type toroid, aluminum foil covered w/ 12 inch radius using 3" 
aluminum dryer ducting.


Problem is, I have to set the Gap to around a 1/16th of an inch to get
any 
sort of stable usage.  Any larger than that, and the coil will fire 
repeatedly for around 2-3 seconds, the go dead, pause and repeat.  I've 
tried the gap, different cap's, coupling etc.

Any hits/suggestions??
Thanks
Erik
