Title: Bally 5500 Photo Transistor Part# Post by: dragster73 on September 18, 2009, 04:34:31 PM I have a 5500 machine that was giving me ERROR #24 coin Reverse. I took apart the coin board under the comparator and i unsoldered the two photo transistor and reversed their positions. I know get ERROR #20 which says coin jam. Based on this i know one of the Photo transistor i swapped from the bottom to the top is bad. I was not able to get the part number off the photo transistor itself. Does anyone know what the part number is? This is the three legged round photo transistor that looks gold plated.
Any help would be greatly appreciated. Thank You in advance. Jerry Clause Gameroom Service. Title: Re: Bally 5500 Photo Transistor Part# Post by: TZtech on September 18, 2009, 05:58:58 PM Hi
