Re: primary tap construction

Hi Bill, I use an alligator clip to tune my 3/8" primary tank. A 18ga.
copper stranded wire is used as the connection medium, it is a 40kv max.
white jacketed silicone coated cable and is very supple and easy to work
with. I got this wire from Surplus Sales of Nebraska. This works great
for my triple modified 15/60 neon bank. The alligator clip was taken
from a heavy duty test clip that I got from Radio Shack I brought a bag
of their best prewired test clip wire sets for about $7.00 and sacrificed
one of the six leads in the bag to get a useable primary clip. These
test leads do not look like an ordinary straight alligator clip, they are
rather wider and have an offset jaw that will clamp beautifully around a
copper tube primary without fear of the clip slipping away from the
tubing. They look more like the jaw of a T-Rex! With all the teeth up
