Re: [TCML] charging reactors

Hi Jim,  Most of those pictures are of other peoples coils but I can tell 
you more about the big coil I use the charging choke on.  The secoundary 
winding is 12.5 inches in diamitor and about 50 inches long wound with 19 
gage wire.   The primary coil is a flat spiral, taped at the tenth turn. 
The primary capacitor is about a .085 uf.
