Rebuilt a Crosley 02CB for a friend, several years ago. had concentric shafts for band switch and another function (Tuning?) that I can't remember. I could not get the 2 parts loose for love or money, including heating with a torch (plumbing) and quenching with Liquid Wrench at the joints, to no avail. Went scary and whipped out the Dremel and cut a slit in the outer shaft. This did 2 things. Allowed the collar to expand a little and provided a "trench reservoir" for the Liquid Wrench. After another application of heat, I finally was able to free, remove, clean, lube and reassemble. Outer shaft was aluminum (if I remember correctly), inner shaft was brass. Dunno why they seized, no major corrosion, mouse leavings, etc.

While this would be radical surgery (I hear you all cringing!) if this was a Walton, Stratosphere, Scott, etc. (Pick your top of the line radio), it was a Crosley. and that "mod" was nothing compared to the need to completely replace EVERY wire in the chassis along with all the caps and many resistors. Fortunately, a big chassis w/ a lot of triodes instead of multifunction tubes in the AF section) so much room. BTW, dunno if this was a cost savings or what, instead of PP 6V6 or 6F6, this radio had 6AC5s in Class B., very rare in radios of this vintage that were not battery farm sets.

Put in a Radio / Aux sw and different size jacks in an external box (Radio had jumper type phono input terminal board. Owner can actually play his guitar through it not enough gain to overdrive, but that Magnavox speaker IS 80 years old.
