[TCML] CW magnifier

[Carlos Van Camp]

Thanks everyone for the feed back.
Yes, I take your point about the CW coil already increasing the coupling, so 
your probably right... No real advantage to going to a magnifier...
My main reason was the ever search for longer arcs! I have a large CW coil 
(valve driven) that is not putting out the arc length I need, so I am just 
looking for ways to improve it...
I am not ready to go down the full electronic driven path at this point and 
I dont think I have the knowledge to pull it off anyway.
So I will stick to my valves, and look at pulsing it to improve output...

Thanks,
Carlos
