I found it amazing to see a radio that new to use an electrodynamic speaker.
The speaker frame is even stamped "Crosley". Not a rubber stamp, but a stamp in the steel, so evidently Crosley made the speaker themselves.
If you change the speaker, the filtering supply has to be changed to an R/C network, with higher value electrolytics, in order to use a PM speaker.
