Hello, i have a MOT 4 stack that i use to power my 4" coil.  I 
origonally used a ballast to limit the input current (25 Ohm 
impedance / 4.5A current draw), but when i took the ballast off, the 
transformers drew over 20 A at as low as 50V.  I would bring the 
voltage up using my variac and the 20A fuse would blow at as low as 
50-70V.  I did this 8 times blowing 8 fuses in a row.  I took the 
ballast off because i was only getting about 6-8" arcs from the 
topload.  So I have no idea how my transformers are drawing that much 
current, can anyone help??  That would be great, thank you!
