This board will fix those 'flaky' trough ball issues once and for all.


-Direct replacements for the original boards.
-Holes for Infrared LEDs are oversized to make it VERY easy to change faulty LEDs in the future
-Tracks coming from LED pads are beefed up to prevent lifting when soldering (if you ever need to)
-No electronic knowledge required - simply remove screws and plugs and new boards mount in exactly the same position as the originals
-Additional NEW 2 LEDs mounted on the TX board indicate operation of the 7 TX LEDs - visible by looking through the coin door
-7 LEDs indicate when RX beam is broken - makes confirming operation very simple
-No modifications at all to the original machine in any way and NO soldering required
-Both LM339 ICs are socketed using high quality "turned pin" sockets
