RF chokes and other Q spoilers
Original poster: "Resonance Research Corp. by way of Terry Fritz <teslalist@qwest.net>" <resonance@jvlnet.com>
Insert a 500 to 1000 Ohm 50 watt resistor in series with any choke that you
use. This "spoils the Q factor" of the circuit and reduces any oscillation
energy near your transformer. Also, off each NST bushing use 3-4 .001, 10
kV caps in series connected to ground. This allows a low impedance path to
any remaining RF currents before they can enter the xmfr windings.
Terry Fritz has designed an excellent filter which is available in the
archives section.
