I'm bringing this thread back to the top because one of the photos above illustrates my situation/question. Last summer I picked up a rusty, rats-nest Model 645X, run 3. As received, the wiring on the tuner rotors was as shown in the left photo. It shows a wire connecting the detector and oscillator rotors, just as shown in a photo earlier in this thread.

This appears the same as in post #8 above, but the connection is not shown in the schematic. Actually, in my case, the wire was not soldered to the oscillator rotor terminal--it was just sticking through the hole. I finished a satisfactory electronic restoration without the questionable rotor-to-rotor connection. But I'm still concerned I've missed something functional.
Does anyone know what this extra wire is for?
Grateful for All Advice,

(I also have to give a public "Thank You" to Chuck Schwark who provided the information which enabled me to rescue this radio.)
