thank you. i dont think im gona mess with the flybacks but there still
hooked into the pcb so i was trying to get one of them running with all the
stuff on the pcb, but never found the power switch. it was froma tv/vcr so
its a pain. now i also just got a ignition coil. i saw a guide on how to
hook it up using a 2uf cap i think it was 2, any way i used the cap from my
MOT at 1uf, i get NO sparc from it, i hooked it up just how they sayd to on
a webpage(dont rember wich one now) but im getting my 7.5kv NST today. now
ill run a nother idea buy you guys now


i wanted to build a REALLY small TC i was gona use a 1" pvc pipe for the
secondary and then just make the rest. will my 7.5kv nst blow it up? or just
not work. and if i got my ignition coil working could i power the little
coil buy it?


Thank You verry much and sorry for my N00bness
