Re: pri-sec elevation (was Magnet Wire Sources)

Dr. Resonance,

What would you advise for a twin TC setup?  Of course the composite primary
is divided into two separate primaries, each about half the normal primary
inductance.  That being the case, it seems like the optimum elevation of the
two secondaries will be less than for a single primary-secondary coil of
equivalent size.  Any practical experience-based comments?

Thanks,
Steve Young
