[TCML] pics of new coil

[Brandon Hendershot]

Hi Norm,
Ver nice clean looking coil you got there! I'm curious, how do your  
primary taps work? It looks like needles sticking out of there, do you  
just loosen the screw and push the needles through the insulation with  
your fingers, or how does that work? It would be cool if turning the  
screws moved the probes in and out.
