  • Annotazioni
  • The K-70 Series was United Reproducers' last attempt to gain a large share of the radio receiver and speaker market. The two models in the series were the K-71 and K-72, also known as the Kylectron 71 and Kylectron 72. These models were identical in every respect except that the K-72 had front folding doors while the K-71 had an exposed grille.

    These receivers both had United Reproducers' unique, patented Kylectron electrostatic speaker. In the last months of 1929 the Kylectron speakers were optionally available in United Reproducers' Peerless and Courier receivers. The K-70 series radios had phono input, push-pull AF output stage, and an unknown type of ballast tube.

    When the K-70 advertising campaign started, the company was already in receivership. The radio market was intensely competitive and the country was facing the Great Depression when the receivers were first available to dealers. Few K-70 radios were sold before United Reproducers discontinued its operation.
