  • Notes
  • Zenith introduced an early K725 model in 1952 and a version with "tube Saver" in 1953 - and 10 years later this family of quite different models (in case and chassis), K725B, K725C, K725L and K725W with the same chassis and case - in the different colors. We call them "late" since one might not see the suffixed letters on the model. Please be careful where to place your pictures. This model K725W is in color shite or ivory.
