Re: [TCML] tcml primary self c

Hi Phil,

Slicing up the ribbon is a neat idea. Actually, adding some holes might 
be a clean way to do it and keep it mechanically strong. Funny, I 
remember using copper bracket ribbon which has a series of holes along 
it's length of various sizes. That might have been an ideal ribbon 
primary (ugly, but it should help displace the currents from the 
predominant edges).

I agree that Chris is only experimenting and the ribbon loss area for 
him is something to keep in the back of his mind (given the 2MHz goal), 
but nothing that should stop him from going forward.

Regards,
Bart
