I have noted from the clear images that this radio relies a LOT on riveted connections to the chassis. Mechanical connections to dissimilar metals can develop a problem at the "joints"...
I suggest soldering all those connections to the chassis or drill out the rivet and replace with serrated washers and hardware.
Since troubleshooting has centered around the oscillator, the mount for the tube socket and antenna/oscillator coil may rely on these riveted joints, solder them securely. A DC ohmmeter will not disclose the issue...
