You still need to put a large capacitor in parallel to the line from
filter to coil driver. As someone else mentioned this should be at
least as large as the capacitor in the driver. Filter would have to be
able to handle the total line current due to extra capacitor and coil
driver. Dooable but a little expensive and complicated.

Doug,
There are brands other than Corcom, but that is a name that comes
easily to mind. I recall a discussion on the Hewlett - Packard
discussion list a while back about a different brand that was subject
to messy self-disassembly failures when they got old. I can't
remember the specific name, or find the discussion any more, but it
wasn't Corcom.
No relation to any of the sellers. They are also often found at
Hamfests, if there are any in your area.
Much easier to use a prepackaged line filter than to try to construct
one from scratch by yourself.
Using RF bypass caps as Bert and Bill suggested in addition to the
line filter will help as well.

Hi Ed; Thank you for your reply and thanks also to Dave and Miles for
your replies. What I have is a dual ignition coil, dimmer switch and
24uf/370v motor run Cap setup and this thing is really "HOT'! I
didn't realize how "HOT' until I powered a 12 inch lightning screen
with a 5 inch center plate on it. I had used the HV supply with a
Jacobs ladder and other stuff with no problems. When I powered the
lightning screen with it, which is really just a lop-sided Capacitor,
it really back fired! took out a fluorescent ballast on the same
circuit and fried the mains outlet it was plugged into! Luckily the
mains outlet was remote from the wall outlet, like an outlet box with
a cord which was plugged to the wall.
I tried to find something on [Corcoms] as some suggested but could
nothing. What I was hoping was that someone could supply me with a
diagram with component values, that I could build, on the order of
the terry filter.
