Today I was working on an 218 "Woodie" datecode N3 with case style 3245. Below I've attached a picture of its cell/component coil assemblies, along with a spare I had sitting around for comparison. I assume the odd coil coloring is just patina/aging? I have seen some oddly colored coils posted before and thought this may be of interest to the forum.
I'm getting proper continuity and resistance readings, but I think something's bad in the component assembly as this was a non-hummer. (Not sure how to test the transistor or capacitor short of desoldering, any advice appreciated!)
Edit: things were just gummed up on this one - a full service has this thing running perfect, despite the weird coils.
