  • Notes
  • Known models is this series are K731R, K731W, K731M, and K731L.  All of these models have wooden cabinets.  The letter designation at the end of the model number denotes different cabinet finishes.  Model K731Y would denote an ebony or black cabinet finish, and no models are known to exist.  This model also does not appear in Zenith advertising, whereas the other models do.  The only reference to this model is in the parts list that is part of the referenced Photofact.  This reference probably is an error and there most likely is no actual model K731Y.
