Hi again Aaron,

I don't use a choke...that's a subject of much debate on the
list, and the general consensus is that they can create more
problems than they cure.  If you look closely at the shot of
the PDT on my website you'll see a horn gap sitting atop the
transformer.  That is all the protection I use, and it works
just fine, firing only very occasionally when the coil is a
bit out of tune due to environmental changes.  The leads to
the gap are short and direct and the gap itself is made up
of scrap 1/4 inch tubing left over from my primary.
