Re: Why do TC's use line filters wired in reverse

Hi Ray,

The choatic performance in a spark gap driven system such as our TC's puts
a lot junk on the line. The
idea is to filter the AC mains from seeing as much of this junk as possible
since the line is also tied
to our houses and appliances. The idea of reversing the filter is then
obvious. However, I must agree
with you that it may be ineffective. I think it would be a good idea to
come up with a better filter
design for our coils which is designed specifically for TC's.

Take care,
Bart A.
