Kenwood KR-7050
A high-speed DC stereo receiver from Kenwood's late-1970s flagship line, known for strong power and precise metering.
Overview
The Kenwood KR-7050 is a stereo receiver, the smaller sibling of the KR-8050. Kenwood marketed it as a "High Speed DC Stereo Receiver," and it sat in the premium part of the lineup during the golden era of hi-fi. Owners note its excellent FM tuner and strong amplifier section. One calls it "a true colossus from the golden age of the hi-fi audio." It was expensive new - $675, or approximately 660 US-$, in 1979 - but it still has a following among vintage audio enthusiasts. One forum user recommends it specifically to Kenwood receiver fans.
