RE: [TCML] Terry filters



Hello,

It was recently pointed out that *RF* grounding the innermost turn to the
core and connecting to the bottom of the secondary and maybe the inner most
primary turn ala Odin coil may be of value. 

What about a half Terry Filter or Dr. Resonance's air core coil?

Hi Rich,

Sure, it wouldn't hurt to filter. But you will need to reconfigure the 
circuit for the power supply. The TF circuit itself is for center 
grounded transformers up to ~250mA.

Take care,
Bart
