Post Subject: High voltage air-capsPosted by Paul Scearce on: 7/19/2005
Romy,
There are transmitter air caps available which can handle several killovolts. They aren't cheap, though, and may also be impractical due to their size.

Check out the Johnson capacitors, particularly the 153 and 154 series.
I suppose you could try adding an air-cap filter after the Electrocube coupling caps to test out cv's theory that the impedance is just too high to drive the 6C33Cs.
By the way, when you chose the coupling cap and voltage devider value, did you take the input capacitance of the 6C33C into account? They will have something like 75-100pf of input capacitance. This might make a voltage divider of its own with the 410pf coupling cap.
