Yes it does, although this initially seemed to be 'parasitic' to me, it's
intentional.

The capacitor definately slows down the discharge of the primary (and the
secondary I believe). This at first seemed to me to be a compromise in the
name of arc supression. It's not though. It actually helps!

I think the LC theory has put me at a disadvantage here. But it's like you
said at the outset of this thread; " I learned a long time ago, that when
theory conflicts with reality, a wise man changes his theory. I am not a wise
man yet, but I am working on it!" Well I'm having to un-learn some of those
theories to reconcile living with Triumphs!

I have a couple of schematics that I'm getting ready to send to you as email
file attachments. This is not something we want send to the list at large
though. It would consume lots of B/W, annoy lots of folks (especially mjb
I expect) and it doesn't work very well. Majordomo probably has a mechanism
to filter out this type of taboo. It really screws up some digests (other
lists)
that I am on. Other than file attachments, there's alway ASCII art.
