16B Code 125 fine tuning assembly - streetmechanic - 12-12-2022
Sometime in its past my 16B either took a hit on its tuning knob or somebody clumsily tried to disable its fine tuning function.
One of the metal tabs at the back of the assembly was bent badly enough to release the smaller (7/64) bearing balls. I found
four of them but I have two questions: (a)were four bearing balls all it ever had and (b)where do the balls go; or more
specifically, what acts as the outer bearing race? I'm guessing Philco never published an exploded view of this but a good
photo of an undamaged assembly would probably tell me what I need to know.

Don't know if helps but it's the only 4 band 16 I've got (code 127). I don't want to take it apart as I have toooo many things apart already. Typically the small ball bearings would go at the far (small) end of the inner shaft or slow tuning shaft.

Radioroslyn- Thanks for the photo and response and I agree with you completely about not having multiple receivers apart at
the same time. The tuning mechanism you show in the picture looks exactly like mine but the bearing balls I need to find a place for are behind the oblong steel piece near the center of the image. Looking at my picture of the disassembled parts, it's actually the three large bearing balls that go on the end of the (steel) vernier shaft- the little bearing balls ride in the groove visible on the brass coarse-tuning shaft. I might be wrong about Philco never publishing info about this mechanism since the brass
bushing and its knurled locking ring seem to invite repairmen to dial in the bearing preload they want and Philco would probably
not assume everybody would understand this without instruction.

The more I play with this tuning assembly the more obvious it is that this was never meant to be repaired if it was damaged this badly. So... I guess I'm looking for somebody parting out a four-band (Code 125 or later) Philco 16. Any suggestions?
