Replying to myself here.  I was looking at things wrong, the opto's are good, the mech control board has a problem.

So I don't need the opto switch anyway.

I can't find a part number for this.  Same part for a lot of other models, this one is actually for an RI-3.  Anyway can these be bought anywhere?  I've seen some used on ebay but sure would like new.  I can most likely make one if I really have to but trying here first.   I just emailed A&B in NH but they are closed today so I thought I'd look for other leads in the mean time.  I believe this is the same part for these jukes:  RI-3 / RI-4 / CTI-2 / R-84 to R-94
