Hi Matt,

Those are the same "type" as the ones I used to sell but the value is too
low.  If you were going to make a 10nF cap for a 12kV transformer, you
would need:

12000 x 1.4 / 1250 = ~13 caps per string.
1.8nF / 13 = 0.1385nF per string
10nF / 0.1385 = 72 strings
72 x 13 = 936 caps!!

If you used the Geek's caps:

12000 x 1.4 / 2000 = 8 caps per string.
150nF / 8 = 18.75nF
So you need 15 caps to get 10nF

15 x -at-2.25 = $34

If you could get the 100nF still:

10 x $1.80 = $18

Cheers,

	Terry
