Unpotting a Neon Transformer

It has been said before that most neon transformer failures relate to the tar instead of the actual windings.  (Carbon
tracks that form inside - especially when used to power Tesla Coils!)

So I took the hammer and chisel and some spirits and unpotted a 9kV 60mA and a 5kV 120mA...

9kV 60mA

5kV 120mA

The tools!

Added one output wire to 9kV 60mA

Needed to redo both output wires on the 5kV 120mA

Side by side for comparison - left 9kV 60mA, right 5kV 120mA
