Mallory Hyfire Ignition problem

IDK if the old Accell Square top Super Coil is compatible with your Ignition Amp, but that coil has been going strong for me since about year 2002. I mounted mine horizontally on the apron, closer to the front, with about a 2.5ft coilwire.
Those are troopers. There was a guy at Pomona that was selling them new open box for $10 a piece and he had about 50. I think they were scratch and dents from PAW (yeah, it was that long ago).
