Hmmm, when I tried a jacob's ladder with it it got one single hot spark
and the tv would turn off. Then I used high series resistance and it
worked. Sort of.
I think I not what did the limiting now that I took the TV apart. There
is a single loop on the core that goes to a TRIAC in the main power
supply. Perhaps if this recieved not enough current the power goes off
because it think's there is a short somewhere. In the future I might try
just putting a small 1 amp transformer on the TRIAC's gate to keep the
