.......This is an AC/DC chassis with a series filament string, and it uses a resistor in parallel with the dial lamp instead of a tap on the rectifier filament. Just for fun, I tried a 6 volt AC/DC bayonet base LED lamp in place of the 47 lamp. The LED worked!  It did not dim as much as the 47 lamp does while the filaments warm up, and it worked well overall. Good to know! (I put a new #47 incandescent bulb back in after conducting the experiment.)

Ron, just curious why you thought it might not work?  And was the LED brighter than the 47 after warm up?

That's a nice looking radio and since the clock doesn't have any alarm settings or other knobs the new electric clock motor should have minimal cosmetic impact except for a purist collector.  In fact, for a non collector wanting a working radio for display, this would be ideal with the new finish, clock movement, chassis rebuild, and new dial covers.
