I'm having trouble with the popper opto boards on my JY and I'm discovereing the opto boards (and full popper assembly) are out of stock worldwide. Seemes like the opto boards are unique to JY.
The ones that are already on my machine have been hand made by someone before me and they need replacing. A-21517 and A-21518.
Does anyone have advice on how I can move forward?
Thank you
Borygard ( Rob Anthony ) has Williams optos. Transmitter and receiver. Scroll a little over half way down the page :

He does board repair too.
Are you sure yours are bad ?
LTG : )
Actually, im going to need to replace the boards, mine cant be repaired.
Where do I go for those parts?
If you can't find board replacements (I would still look for the original PCB's) I would try replacing the led's/diodes on the A-21518. I was having intermittent issues and the most common issue was the transmitting LED's. When I replaced all my LED's I noticed that they had gotten yellow most likely from age. The replacements diodes were clear - Bally/Williams WPC system LED-IR diode 5671-12731-00 Just a suggestion.
