[TCML] Suitable MMC Capacitors

[Paul Brodie]

That is the correct list I was telling Brandon about but it is going to be 
of little help.
Brandon, you are not building the type of MMC that is usually being built by 
other TC builders.

For everyone to understand what is going on, I was attempting to help 
Brandon find some caps to use to build a tank cap as inexpensively as he can 
and still work with his 15kV 30mA neon sign transformer, as he is on a very 
tight budget. The caps we are looking at are only selling for 3 for $12. I 
located these caps at Fair Radio for him that are rated .01uF at 10kV. He 
wants to use 4 in series to get .0025 at 40kV and put together 3 strings of 
these to get .0075 at 40kV. I actually recommended 3 strings of 3 caps to 
get more capacitance, .01uF at the lesser voltage of 30kV, but he wants the 
extra voltage rather then the extra capacitance and says they will fit his 
budget. JavaTC recommends .008uF for his setup and I have always gone with a 
little bit more capacitance rather than less when given the choice. If he 
had the money, I would actually prefer he went with 4 strings of 4 caps to 
get .01uF at 40kV but I suppose that is immaterial.

So has anyone got any advice for us, taking into consideration that the 
usual Cornell Debilier caps are out of the question due to cost. If you make 
a recommendation, please try to keep the cost under about $50 for the caps. 
That has been a very stiff requirement for me to meet, so far. Thanks 
everyone.
Paul
