I was looking at the receiver, and one of the guys said, “You want it? Take it. Don’t work.”
I figured what the hell, took it home, opened it up, took a can of compressed air and a brush to the interior, deoxed all the moving parts, replaced the power cable, tightened some screws and other connections, plugged it in, and it fired right up.
Considering that more-gently used samples of the KR-4070 are selling for triple digits on eBay, this is a heck of a deal for a good late-Seventies receiver with a solid 40 watts per side. And 40 watts, I think, is probably the sweet spot: lower-powered models tended to be stingy with the features, and high-powered jobs don’t necessarily sound any better. My mid-Seventies JVC checks in with 42 watts per channel and has every control I want and several I don’t.
I hope the Kenwood’s dial cord is still properly strung. These didn’t often fail, but they’re a pain to rework.
(I owned an earlier Kenwood, the KR-5150, for about a year, but swapped it off for the JVC, lured by the siren song of Seventies surround sound.)
