Joe, all:
Thanks for the pointer.
I did move the primary tap. Bart's formula called for a perfect match at 16
turns so that is where I started. But I moved it in and nothing.

I suspect that the MMC has a problem. Even if I were 5 or 10% out of tune
I'd get streamers even if they were 1" long. But no streamers at all means
to me that the secondary/primary are seeing zero. That says that the MMC is
doing nothing.

I will swap out my old, working .0117µF MMC tonight and see if I get
anything.

Safety First!

Ted

Heya

I still have yet to make my first coil (parents, mother actualy) but from
what I have seen in the past posts
along this line you may want to check your tuning on the coil. Try sliding
your tap around and see what
happens. Good luck
