• Jewel Wakemaster 920.

  Original model came in either walnut or ivory plastic cabinet

  Nearly the same as the newer Jewel Wakemaster 920A model, however the chassis is not shielded on the sides, nor is the 12AT6 detector tube shielded as with the 920A. Most notable difference is that the 920 uses a 140-4 clock with two knobs, whereas the 920A has a 140-6 clock with three knobs and a 60 minute timer.
