I called and talked to the guy at Paramount. I forget his name. I'm horrible with names. He hooked me up with the company he uses to get his meters rebuilt. Damned expensive stuff.
At one point, I had the machine working with points, but I've yet to get I to work with anything else.
It's an Allen 22-250. I'm sure Tuner could get me fixed. I need to call him.
Maybe make your own magnetic pickup amplifier. I think Tuner posted or PM'd me that can be done with a good genuine GM HEI module. It would need a power supply but probbaluy not too hard to figure out.
