metalized polyester film tank capacitor for a vacuum tube tesla coil?

Can you use a mpf cap in a vttc for the tank circuit?

I don't think so, you want an air-gap I think.

Are you talking about a vacuum capacitor? I'm not talking about a spark gap tesla  coil, i mean a vacuum tube tesla coil. i know mpf cap isn't good for sgtc because of the harsh pulse, but the vttc is cw (continous wave) so there is no pulse. thanks and please answer.

If its the topology I'm thinking of, all the caps need to be >>10kV operating. What's your circuit ?

It's xellers vacuum tube tesla coil on instructables.

If the cap's rated at >10kV you'll be fine. Like Xellers says, its a class C circuit, so there are high resonant peaks on the cap.

so it doesn't mater the type of cap?
Not here too much.
