feeding a moving coil speaker.
Below are a couple of photos of a radio, recently
added to the KB Museum, which
appears to have the same chassis as the KB 333 but in a different cabinet.
The radio has been fully restored, including some new wood panels.
The combined volume/reaction control appears to have been changed at some
point for 2 separate
controls, the lower right one is the volume.
This radio has solid brass escutcheons for the wave change and tuning
dial, not Bakelite ones like the KB 333.
