Tech experts... I have a Bally Fireball 2 and the game has been working great over the past 6 months. Recently, I noticed that the speech was not working or would work at times but not other... The sound is working fine. Also, it appears that the machine when not being played has a "static" sound (almost like listening to the ocean in a conch shell except louder). I have done all the routine things like reseating the connectors but really don't know where to begin at this point. Any suggestions? I assume it has something to do with the squawk talk board?
