Wouldn't the parts diagram in the manual be the definitive source? They are not listed in The Hobbit diagram, specifically I'm on pages C-18 & C-19 for the flipper assemblies. I ordered replacement coils from JJP when I first got my machine, and there was no mention of this part in my dialogue with them either. The upper flipper I'm rebuilding had a replaced coil there and it was poorly installed in several ways and has given me trouble since day 1, so I'm not sure I trust that the diode is correctly placed there.
For what it's worth I had the correct JJP coil on hand and did the rebuild before I saw your latest reply. It plays fine without the diode although I don't want to risk damaging the machine, so I will order them and leave the game off for another week waiting for this 11 cent part to arrive! Guess I'll order some extras.....adding photos to show replaced, and what appears to be factory left and right coils which are different in their diode layouts
