  I just unpotted the first of four neon transformers that I got from a
sign shop in town. The guy there told me they were 15Kv -at-30ma. I'm sure
they are 15Kv but not so sure about the current rating as the plates
have all been removed. I kind of went back to the dark ages in the way I
removed the potting. I boiled them in oil! I used a burner out of a old
space heater to heat the metal pan pan filled with diesel! I know this
sounds dangerous folks but it was a good 20' away from anything that
would burn including yours truly. It really speeds up the process as it
uses solvent and heat to disolve the tar. Just don't try this at home
folks! The core looks, and disassembles the same way discribed in the
archives. One secondary reads megohm resistance and is probably fried.
The other reads a little over 8kohms. Is this the usual resistance of a
15kv secondary? Or is this side shorted???
