[TCML] Q,,question

[resonance]

Litz wire would be ideal for the primary if it were not necessary to tap. 
It's a nightmare to properly tap and get solid connection to all strands.

Fine stranded copper welding cable works good and is easy to tap.

The best option, really, is copper tubing.  It's hi-Q, easy to tap, and you 
can use larger diameters if you need less resistance.
