Cardboard secondary forms...
Greetings,
My experience with a cardboard secondary tube was poor. Admittedly it
was my first coil, but it shorted out by arcing through the cardboard and
down the inside. I would suggest, as Ira Groff pointed out, that if you
use this type of secondary coil form, coat it with something like an
epoxy resin first.
