I'll bet it is to all awnsers, ever been tickled by it ? 70 Kv that should put you into orbit quite nicely. So with it being transistor fired does it still use the old points as the trigger or is it electronically triggered as well, oh hang on you have had it since the 70's so it would still be points fired at the distributor. What is the voltage AC or DC because I am not sure if electronic circuits use either ac or dc voltages.
