To all who suggested LEDs, thanks for the suggestions but there is a
problem. These are not pilot lamps. They illuminate an LCD and need to be
controllable by a regulator circuit for intensity. LEDs aren't really
suited to this application, although some modification of the circuitry and
optics might make it work.

All I want to do is get some more incandescent lamps for this radio, and
keep it close to original.
