Uher SG-510
Uher's bid to put a real open-reel machine in the hands of anyone who'd been saving for one - for under $400.
Overview
Uher built its name on recorders that felt engineered rather than assembled. The SG-510 was the machine the company used to argue that you didn't need four figures to get that experience. In its own advertising, Uher pitched the SG-510 as the "affordable alternative" for anyone who had "dreamt about owning a Uher recorder" - a 4-track open-reel stereo machine with an "uncommon low suggested retail price of under-$400." The buyer was the listener who wanted genuine Uher build quality and reel-to-reel sound but not the professional price tag.
The feature list gives people what they need and nothing they don't. Uher's own copy said so: the SG-510 "has everything a listener would want and nothing he doesn't need." Peak-reading meters handle record-level control, so there's no guessing at overload. Automatic shut-off handles the end of the reel. The transport runs at 7½ and 3¾ ips, which Uher noted is good for "up to six recording hours" of material. For a home deck that's a sensible pair of speeds. The fast one suits serious listening and archiving. The slow one suits long unattended captures where tape economy matters more than the last word in high-frequency response.
The SG-510 doesn't force you to own a separate system to use it. Internal speakers and amplifiers mean the deck can work as a self-contained recorder or as a deck feeding something else - Uher's copy made a point of that dual role. Inputs cover microphone, radio, and phono, so the machine can sit at the center of a modest hi-fi. Calibrated controls and a digital counter round out the front panel. The whole thing plays horizontally or vertically, and the vertical orientation lets the deck tuck against a shelf or wall instead of eating a tabletop.
Uher described the SG-510's specifications as "very competitive specifications normally found on more expensive recorders." The headline figure was wow and flutter of less than 0.08%, which is respectable for a consumer deck. Uher also called the SG-510 "built to Uher's typically rugged specifications," the kind of claim every manufacturer makes, though it carried some weight with buyers who trusted the brand's field recorders. Treat the marketing as marketing. The wow-and-flutter figure and the feature set together suggest a deck that was simplified rather than stripped down.
HiFi-Stereo (June 1976, p.100) ran Uher's "affordable alternative" advertisement for the SG-510, which is where the price, speed, and feature claims above originate. That's the company's own voice, not an independent verdict — worth keeping in mind. What the period trade press does confirm independently is that the SG-510 was a real, actively distributed product rather than a paper announcement. Photo Acoustics Ltd., Uher's official UK distributor and main service agent since 1969, listed the SG-510 in its dealer price tables. Studio Sound (May 1977) shows the deck at £160.00 through that distributor, and a later Studio Sound (February 1978) listing puts it at £155.00. Interphoto Equipment, another UK seller, advertised an "SG510 Steromatic" at £139.31 plus VAT in Studio Sound (June 1978). The spread across those figures — roughly £139 to £160 depending on dealer and date — is normal for the era and tells you the SG-510 was a commodity item competing on price, not a halo product held at a fixed premium.
By the end of the decade the SG-510 had moved into the used market, which is where most surviving examples come from today. A classified listing in Audio (July 1980, p.?) offered a used SG-510 at $175, a little under half its original suggested price. The same classified columns carry Revoxes and Technics decks, bought and sold by people trading up, down, or sideways through open-reel gear.
Anyone considering one today should go in with clear eyes. The SG-510 is a consumer machine from a company better known for its professional and field recorders. The features that made it attractive in 1976 - internal speakers and amps, a simplified transport, two speeds - also make it a different proposition from a studio deck. The internal amplification and speakers are convenient but not the reason to buy one. The reason is the transport and the Uher build. The wow-and-flutter claim of under 0.08% is the spec to verify on any example, because it's the one number that separates a healthy SG-510 from a tired one. As with any open-reel machine of this age, belts, pinch rollers, and head condition are the usual suspects. Since the deck mounts vertically or horizontally, confirm it sits stable in whichever orientation you plan to use.
