[Jukebox-list] pin bank cancel coil...

[Wesley Dean]

    Justin, since the SC switch also operates the pop meter coil, it may help to disconnect it. I have also found that a 2.2 K capacitor fed through a diode and a 680 ohm resistor stores enough energy to pulse the pin reset coils. With this in place the SC switch can stay closed in play position. Wes
