[TCML] 833C VTTC Audio Coil

[resonance]

7.2 kV pole xmfrs are quite cheap these days.  We unwound some of the turns 
from the outer sec winding to creates a 4.5 kV AC rms high voltage source 
for an 833C coil but have not yet built the coil.  These xmfrs can provide 
1-1.5 Amperes at 4.5 kV at low cost.  And, being immersed in coil, they are 
nearly bullet proof.  We use a simple multiple parallel resistor network 
with a small air core RF choke to provide some sec coil protection.

Regards,

Dr. Resonance
