Hello Jim, Coilers,

Use a microwave oven transformer.  Remove the old high voltage
winding and the filament winding but leave the primary intact.
Wind a new secondary using number 10 wire which you can buy at
Home Depot or most any hardware store.  You'll need about five
or six turns, since most of the MOTs that I've played with are
one turn per volt.
