Peter, All,

Megahenry Brand chokes are a high L , high voltage holdoff, air cored RF choke 
which I manufacture on a custom basis for Tesla coil use.  They have 
proven very effective in keeping harmful transients out of neon 
xfmers when also used with a single (not center tapped) transformer 
safety gap.  Contact me off list if interested.
