It doesn't cost much to build a test rig. I'm still using the one my father knocked together in a real hurry back in 1961 or 62 with a 59 Ford distributor on it. I'm planning on building another also with an old Ford dizzy, because they are still quite common and the best test distributor for testing extremes will have at least 8 lobes on the cam. I'm going to add a few more instruments to it along with the variable spark gap. So far, I have sourced a Westinghouse ammeter that was actually used on a DEW Line station in northern Canada (manned by American servicemen) and a NOS Soviet DC voltmeter (ebay from Estonia). I thought it would be cool to have the opposing sides come together on this new test rig! I also plan to have a proper tachometer that will respond to all kinds of inputs, be they current sensing or voltage sensing. Anyway, it does not have to be expensive to work well as a test rig. One good thing about the old test rig is that the distributor shaft wobble has gotten quite bad. That actually allowed me to fine tune the circuit to cancel as much of that effect electronically to obtain a more stable output with points and a worn distributor. A new test rig couldn't have done that, nor could some emulator to provide triggering impulses or one using zener diodes instead of a real spark gap. Fred
