  • Notes

  • Zenith model K666R is an AC operated radio-phono combination AM superheterodyne receiver.
    Sam´s 203-18. This model has broadcast only. See also other models with broadcast ans shortwave (scale) before uploading a picture. By the way: We normally write Cobra-Matic as used by Zenith, but only here we also bring "Cobramatic" to the model type - just to get a result for users who write wrongly "Cobramatic" instead "Cobra-Matic" into the search field. Cobra-Matic is just a brand. Zenith used it for this type of record changer. Record players and changers were often built for Zenith by Webster, Seeburg, BSR etc. - at least until the WW2.
