Dr. Resonance,

It is common practice in the electronics industry to use
shielded xmission line to carry data etc. from potentially
noisy devices. The shield is generally case/rf ground at
the offender (TC) and left open at the end attached to the 
susceptible device (xfmr). I would presume that the added
capacity of the shield would act as additional rf bypass 
to ground and help clean up any hash on the data/HV lines.

Is there a flaw here? I wouldn't expect to see any
significant effects due to resonance at lengths in
50ft range.

George.......
