JVC HR-7650U
A five-motor, front-loading VHS stereo deck that a period reviewer flatly called the best VCR he'd yet used - with one honest caveat about piano tuning.
Overview
Twenty-six and a half pounds of front-loading VHS, measuring 18⅜ inches wide, 6 3/8 high and 14 3/8 deep. Those numbers tell you a 1982 deck was built like furniture. The HR-7650U, part of JVC's "Vidstar" line, was compact by the standards of its competitors, even at that weight. The cassette goes in about halfway, then a motor takes over and pulls it down into the transport. No pressing, no lever.
That loading motor is one of five inside the machine. There's a brushless, quartz-locked direct-drive drum motor, plus separate motors for capstan, reels, tape wrapping, and the cassette mechanism itself. A lot of decks in this period were still doing clever things with belts and idlers. The drum carries two pairs of video heads - one pair dedicated to SP, another to EP - which is how the deck manages two hours in SP and six in EP on a T-120 cassette. Owners who fed it the newer T-160 tapes could get eight hours in EP. Playback speed switches automatically to match two-hour SP, four-hour LP, and six-hour EP recordings, so a tape made elsewhere still plays back at the right speed without fiddling.
The audio side is where this machine earns its keep for anyone who cares about sound. There are two audio channels, usable for stereo or bilingual programming, with Dolby B noise reduction built in. Audio (December 1982, p.14) walked through the stereo record function and measured a signal-to-noise ratio of just 46 dB even with Dolby engaged. A cassette-deck owner will wince at that, but it was the state of VHS audio in that era. The same review noted the stereo headphone jack and the two microphone and two line inputs, with matching channel-1 and channel-2 outputs on the rear panel alongside the usual video in/out and antenna connections. The reviewer pointed out that those stereo inputs would come in handy "when stereo TV arrives on the scene" - which dates the machine precisely.
On the convenience side, the HR-7650U was loaded in a way that would have been fantasy a few years earlier. Touch buttons with a microprocessor-based logic-control system handle every function. The tuner offers 16 channel presets and 105-channel cable-ready capacity. A 14-day, 8-program timer handles scheduling, including recording the same channel at the same time on successive days. A fluorescent display shows tape counter, clock time, and programmed timer data. A blinking LED tells you the tape is running when you're too far away to see the counter, and a "Tape End" light comes on with about ten minutes of recording time left and starts blinking at five.
The shuttle search runs at roughly seven times SP speed and 21 times EP, in either direction. Audio (December 1982, p.14) found it worked well with good picture quality, though some noise bars were visible during search. Still-picture and slow motion drew unqualified praise. The reviewer called them the best he'd seen, with no noise bars whatever. A slow-motion tracking control lets you vary the playback speed of the frozen or slowed image. Shots can be edited together without picture break-up at the transitions, and there's a direct camera input on the front panel for anyone shooting home movies.
The infrared remote is a real working remote, not a token. It turns the unit on and off, selects channels on the VCR tuner, activates slow-motion playback, pause and still-picture modes, audio dubbing, and frame-by-frame advance, plus record, play, stop, fast-forward and rewind shuttle search. It runs on two AA batteries, with an LED that flashes when commands go out.
The timer, as on most decks of the period, is complex to program. The reviewer admitted as much. It does what it says, though, including the successive-days recording trick and numerous other combinations of 8 programs across a 14-day window.
Picture quality in SP mode drew real enthusiasm. Audio (December 1982, p.14) tested with Maxell HGX cassettes and reported a minimum of grain, good contrast and brightness, and colors that were pure, clean and highly saturated. EP recordings were "eminently viewable" - not equal to SP, but entirely usable. The reviewer's summary verdict was that the HR-7650U was the most versatile, sophisticated and best-performing VHS VCR he had yet encountered, and that it performed flawlessly and reliably during his time with it.
The caveat is the one that matters for anyone buying one today. However much Dolby B helped the audio, fixed-pitch instruments such as bells and piano suffered from what the reviewer called dreadful wow and pitch variations. He attributed this to tape-motion problems affecting all VCRs of the era, not to the JVC specifically, and flagged it as the next big area for improvement, especially with stereo TV and Dolby stereo movie cassettes on the horizon. The suggested fixes ranged from a balanced dynamic tape-tension system (probably expensive) to some form of digitally controlled tape motion.
One unexpected use from the period: the reviewer ran the HR-7650U with a Sony PCM-F1 digital processor and reported great success, noting that the deck rarely required tracking-control adjustments even when playing tapes recorded on other machines. The accuracy and stability of the tape travel mattered for digital audio recording, and this deck apparently delivered. He also noted that head cleaning is especially important when recording or reproducing digital signals.
On surround sound, Jim Fosgate of Fosgate Research reportedly told the reviewer that feeding the HR-7650U's stereo outputs through his SQ decoder and surround-sound synthesizer, with appropriate side and rear speakers and amplifiers, would yield a good approximation of Dolby surround as heard in movie theaters. That's a period curiosity rather than a factory feature.
The sources consulted for this page give no documented production run and no modern repair-and-maintenance literature for the HR-7650U. Those remain open questions. What the record does establish is a five-motor, dual-head-pair, front-loading stereo VHS deck that a working reviewer in 1982 ranked at the top of everything he'd used, with a candid warning about tape-motion wow that no amount of Dolby B could fix.
