I recently bought a Marquette Dyna Tuner - Model 42-132.
I thought it was a great find as I am getting a 1950 Plymouth business coupe back on road.
But, found little or no info on web, as it is missing a probe lead. The Dyna-Tune socket has three female terminals.
I am adept at electronics and have a large resistor/capacitor inventory.
By chance is there anyone that may know what parts the probe has?
I know it is a stretch, but hoping someone remembers.
