Does anyone know what photo-transistor Stern uses on the long range opto receiver? The assembly is #515-0215-01 and the PCB part is 520-6940-01. It is used on several Spike system games. I cannot find a schematic for the assembly.

I have a board that was botched from the factory but it's an easy fix if I can find the part. The assembly is cheap to replace. I just want to repair this and have a spare.

I don't know for 100% sure...
but I'm pretty confident that they don't use a photo transistor.
Both emitter and receiver are Red LEDs.
