Kenwood KW-8077
Six heads, three motors, and a price tag that put it at the very top of Kenwood's tape deck line.
Overview
The KW-8077 was Kenwood's flagship open-reel tape deck at the turn of the 1970s, and the spec sheet reads like a wish list: six heads, three motors, automatic reverse record and playback, automatic repeat playback, and solenoid-action micro-touch transport controls. This was not a machine you bought to dub a few cassettes — it was a serious tape deck aimed at the enthusiast who wanted the works. Kenwood's own advertising, running in the pages of High Fidelity (December 1970, p.158), billed it as "the magnificent KW-8077... 6 Heads 3 Motors Stereo Tape Deck with Automatic Reverse Record/Playback plus Auto Repeat Playback," and for once the marketing wasn't overselling.
The six-head complement is the headline. A typical quarter-track stereo machine of the period made do with two or three heads; six meant the deck could handle erase, record, and playback functions across both directions without compromise, which is exactly what the automatic reverse record/playback feature demanded. Three motors — the drive arrangement listed in contemporary spec tables — kept the transport independent of the reel handling, and the hysteresis-synchronous drive motor was the serious choice for speed stability. Owners report the solenoid micro-touch controls give the transport a light, positive feel rather than the clunky mechanical clatter of lesser decks.
The numbers from the period tell the rest of the story. A spec table published in Audio (January 1971, p.168) listed the KW-8077 with a frequency response of 20–20K Hz ±3, a signal-to-noise ratio of 52 dB, wow and flutter of 0.04 percent, and a fast-wind time of 70 seconds. Those are respectable figures for an open-reel deck of the era, and the 0.04 percent wow-and-flutter number in particular is the kind of figure that separates a three-motor transport from a two-motor compromise. The same table gave dimensions of 17 x 19¼ x 9 inches and a weight of 46 pounds — this is a substantial piece of furniture, not a shelf-top accessory.
Feature-wise, the KW-8077 carried a five-step equalizer system, a search system for locating tracks, an easy tape-loading lever, and mic-line mixing. Remote control was available as an option, which in 1970 was still a luxury touch. The deck was a quarter-track stereo machine (four tracks, two channels), and the spec table confirms it was a two-head... no — the table lists six heads, consistent with the advertising. The deck did not include a built-in power amplifier, so it was a component in the strict sense: you fed it into your receiver or amp.
Price was $549.95, according to the Audio (January 1971, p.168) table — and that figure is the clearest statement of where the KW-8077 sat in the Kenwood hierarchy. The same table lists the KW-5066 at $199.95 and the KW-4066 below it, so the 8077 cost roughly two and a half times the next model down. That was flagship money, and it bought flagship features: the automatic reverse record/playback, the repeat playback, the solenoid transport, the six-head array. Kenwood's own advertising in High Fidelity (November 1970, p.111) positioned the 8077 above the KW-5066 in the tape deck lineup, describing the 5066 as the "shown" model with the 8077 offered alongside as the step-up machine.
The deck was introduced to the American market around the middle of 1970; Audio (July 1970) reported that Kenwood would be introducing a new range of tape recorders including "a 6-head machine (Model KW-8077, featuring solenoid controls and three motors with automatic reverse record/playback." By the end of the year it was appearing in Kenwood's full-line advertising across High Fidelity and HiFi-Stereo (December 1970), and it was still listed in the January 1971 Audio equipment directory. Production years beyond that are not documented in available sources.
For collectors, the KW-8077 is a niche piece even within open-reel circles. It's a big, heavy, feature-dense deck from the transitional moment when open-reel was still the serious audiophile's tape format, and its six-head automatic-reverse design makes it mechanically complex — the kind of machine that rewards a patient technician and punishes neglect. The 46-pound weight and 19¼-inch depth mean it needs real shelf space. Documentation is thin compared to the cassette decks that followed, and parts for a six-head transport are not something you find at the corner store. But for someone who wants a period-correct flagship open-reel deck with the full automatic-reverse feature set, the KW-8077 is one of the more distinctive machines Kenwood built — and the $549.95 original price is a useful reminder that this was never a budget item.
