Has anyone done this successfully? I have seen other posts where people have successfully mounted the sensors on the jackpot ball exit chute on model B type machines, but the Model "A" redirects the winning ball back to the bottom tray to make up the "15th ball" in the jackpot.

There seems to be a 1/4 to 1/3 inch gap on the back of my machine between the jackpot ball exit chute and the lower ball tray return that I might be able to use, but I'm not sure how much gap is required for the sensor to detect the moving ball.

Has anyone successfully set up an "A" recycler for a Gaku counter and if so, where did you put the jackpot sensor?

Thanks in advance.
