Stereo Receiver, the best in FM reception. The finest in stereo sound
New from Kenwood, stereo receiver designed for the FM buff who demands the finest in broadcast reception and who also enjoys the luxury of a complete stereo system. Two integrated circuits IF stage and 2 FETs in the FM front-end, coupled with a 4-gang tuning condenser, provide better than average sensitivity, superior alternate channel selectivity and freedom from noise and interference. Silent, automatic switching from mono to stereo activates a stereo indicator light. A power output of 75 watts (IHF) at 4 Ω and 56 watts at 8 Ω , inputs to accommodate phonograph, tape deck, and auxiliary, 2 pairs of stereo speaker terminals, plus center channel output, with output switch to control speakers individually or together, and Kenwood's famous U.S. patented power transistor protection circuit are among the features that account for the high performance characteristics of the KR-70. the best in broadcast reception, the highest standards in stereo componentry - all at the delightfully low price, including cabinet.
