I've searched thru the manual, but I don't see a part number for the set of optos mounted under the playfield below the whirlpool exit. They serve as switch 62, and the entire set is missing from my Whitewater. I'm hoping to find a plug-in replacement that includes both optos, the wiring, and the connector.

Does anybody know if the complete "assembly" has a part number, and where I might be able to find one? (I've also searched the usual suspects for the part, including PBR, Marco, Bay Area, etc.

Thanks!

Yes, everything is missing: both optos, the wiring, the connector. I haven't been able to find part a-15758 at any pinball parts retailer - any suggestions (it doesn't appear to be on Marco either) for where I can find it?

I'm not sure how much of an issue it is to not have this opto present, since there is another one at the whirlpool kickout, which seems to also register balls that travel thru the whirlpool? Maybe it just means it takes a little longer for the game to recognize that a ball fell thru the whirlpool?

Thanks!

Yeah, I suspected that the whirlpool kickout switch was probably "programmed" to recognize a ball thru the whirlpool in case the whirlpool exit opto wasn't working. I'd still like to install the correct set of optos - the connector is still there that would attach to the opto connector. Do you happen to know if the set of optos, wiring, and connector are common to other games? I'm hoping that it is...
