Just some info.
The Squawk and Talk sound board needs -12 volts for the amplifier. To get this voltage, it takes the backbox AC GI power, and converts it to -5 volts (using a 7905 regulator), and doubles it up. So if the game doesn’t have any backbox lighting, the sound board won’t work. Note the sound board will still boot and flash its LED the right number of times, and will create the sound. Just with no amplifier power, you won’t hear the sound.
Quoted from jj44114:That’s not quite correct.
This info is from Clay's Pinballninja site
