?As I continue to evaluate the 2-B on the bench here I'm starting to see 2nd tier issues that were not immediately apparent. In this example, the lathed/machined tuning shaft is slightly bent! What could have caused that without causing other significant physical damage to the radio? It's like finding a bent shaft inside a three layer cake!

I noticed the tuning knob has some slight but noticeable up and down and side to side play when rapidly tuning from low to high on a band - some wobble, not concentric. Then I noticed the same wobble in the shaft itself.

This isn't purely cosmetic-get-used-to-it damage. I now suspect the shaft wobble and resulting plus/minus dial string tension, however small, might be the cause of several brief dial slippages when tuning across a band.

what are the chances of finding a parts unit with a tuning shaft to spare? And I'd rather take a beating than restring the dial.

Comments, advice?
