Re: [TCML] Tesla Coil not working (probably primary/secondary/top load issue)

Deepest apologies for that last email, accidentally hit enter when I did not
mean to.

Yes, the PFC is before the NST and the filter after it.

I have noticed that it seems to be, this NST is actually one my dad had from
maybe as early as the 70s, and the label definitely said 35 mA.

Haha yeah, I am going to do some running around today and then I will make
the top load and test it out. I just figured it was necessary for good
performance but not necessary for performance at all, so I could confirm
that most everything was working without it.

I did mention it, but I didn't make it very clear. What I said was I tapped
it in 4 different points on the primary coil, which is just a really rough
tuning as in my case I have to strip a quarter inch of wire every time I
want to tune it. Which really  isn't that big of a deal, I am quite willing
to sit there for an hour stripping piece by piece off until I narrow down
where the tap point needs to be, but the problem was I saw little to no
difference in any of these relatively dramatically different tap points. I
was expecting the difference to be whether I get half inch sparks or three
inch sparks, not the difference between sparks and no sparks at all. In any
case I'll throw on the top load and get back to you either way.

I have been using Tesla Map.

Thanks for your reply!
