Sony Model 260 (1965–1967)
A $249.50 reel-to-reel stereo tape system that promised a "virtual curtain of stereophonic sound" — and delivered it with detachable speakers built into the lid.
Overview
The pitch was pure 1965: close your eyes, and the Sony Model 260 would put you at the podium of a symphony orchestra. That's the line Superscope ran in the pages of High Fidelity (July 1965, p.15), and it's a fair summary of what the Radial Sound system was chasing — a stereo tape deck whose two speakers lived in the main case and whose two more lived in a detachable split-lid, together producing what the advertising called a "virtual curtain of stereophonic sound." Whether a four-speaker spread in a portable tape deck actually enveloped a listener is a question owners have argued about for sixty years. What isn't in dispute is that Sony built a serious tape machine underneath the marketing.
The 260 was a solid-state stereo tape system — deck and speakers in one package — sold through Superscope, Sony's U.S. distributor, at a list price under $249.50. That number matters. In the mid-Sixties, a quarter-grand was real money for a home tape machine, but it bought a complete system: transport, electronics, and the Radial Sound speaker arrangement in a single box. Buyers who wanted to step up to Sony's flagship paid under $399.50 for the Model 530 and its four-speaker XL-4 Quadradial setup; buyers who wanted a deck alone could spend under $149.50 on the Model 250-A. The 260 sat in the middle of that lineup, and Sony marketed all six models as "six ways to go stereo, Sony-style" across a run of magazine spreads in 1965, 1966, and 1967.
The heart of the 260's appeal was the Radial Sound speaker concept. Two drivers were mounted in the main case, two more in the detachable lid, and the arrangement was meant to throw sound outward in a way a conventional pair of box speakers couldn't. Sony's advertising leaned hard on the effect — cathedral organ, Bach's Hallelujah, "volcanic power of the bass" — and the copy promised you'd hear "every breathtaking sound" from the highest treble to the deepest bass. Treat that as advertising, not measurement. What the 260 actually delivered was a compact, self-contained stereo tape system that could be set up anywhere there was a wall outlet, with no separate speakers to place or wire. For a family in 1965, that convenience was the whole point.
The machine itself was built for ease of use as much as fidelity. Sony's house features of the period show up here: a Retractomatic pinch roller for near-automatic threading, and Automatic Sentinel shut-off that disengaged the transport at the end of a reel. The 260 ran 4-track stereo or mono, offered three speeds, and carried separate bass and treble controls and a pause control. It shipped with two of Sony's F-96 dynamic microphones, which meant a buyer could record the moment the box was opened — no accessory shopping required. Superscope's literature billed it as "a complete stereo entertainment system for the home, any home," and for once the claim was close to literal.
What the 260 was not was a studio deck, and collectors should be clear-eyed about that. The three-speed transport and 4-track format put it squarely in the consumer camp, and the Radial Sound speakers — clever as the split-lid arrangement was — were small drivers in a portable case, not monitors. Anyone expecting the 260 to record like a pro machine will be disappointed; anyone expecting it to be a charming, self-contained period piece that plays and records 4-track tape with a minimum of fuss will be delighted. The F-96 mics alone are worth the price of admission for someone who wants to make tape recordings the way a 1965 family did.
The 260's run was short — it appears in Sony/Superscope advertising from 1965 through 1967, and then the lineup moved on. That brief window, plus the fact that the detachable split-lid speakers were easy to lose or damage over the decades, makes complete, working examples scarcer than the original production numbers would suggest. The deck's mechanicals are the usual reel-to-reel maintenance story: belts, idlers, and pinch rollers that have hardened or stretched after half a century, and heads that need cleaning and, often, relapping. The Retractomatic threading mechanism and the Sentinel shut-off are the two features most likely to need attention, since both depend on small mechanical linkages that stiffen with age. Electronics are straightforward solid-state and generally repairable, though the electrolytic capacitors of the era are due for replacement in any unit that hasn't been serviced.
For a collector, the 260 occupies an interesting spot: it's early enough to be genuinely vintage, complete enough to be usable as a system, and obscure enough that it doesn't command the prices of Sony's later, more famous tape machines. The Radial Sound concept gives it a story no ordinary deck has, and the split-lid speaker arrangement makes it a display piece as much as a player. The catch is that the very feature that makes it interesting — four speakers in a portable case — is the feature most likely to be incomplete on a survivor. Buyers should confirm both lid speakers are present and working before committing, because a 260 with a dead lid is just a mono-ish tape deck with extra holes.
