Rodrick,
If that doesn't work you can still use the neon and primary
for: 1) put a single turn short of 3/8 copper tubing where each
secondary was and use it as part of a ballast for a pig. 2) Rewind
each secondary with 12 turns of #6 wire. My former 15kV 60mA neon now
put out 7.5V at 65 amps from each secondary.
With the secondaries in parallel I use the 7.5V at 130A for resistance
soldering and electrochemical cells. In Series 15V at 65A for a quick
battery charger.
Regards,
jim
ps. 8k ish is the normal DC resistance for a neon secondary. The
megohm secondary is bad.
My 15kV 60ma neon is 10" by 6" by 7", my 30ma neon is about 1/2 that
volumn.
