Our Thoughts RADAR AI

At £54, this is wildly below the normal used asking range for a Revox B750, where seen-market prices cluster around roughly £500–£1,300+ depending on version and condition, so this is a bargain if it’s complete and basically working. Even a rough, unserviced example would usually sit far above this, so the only way this is not a steal is if there’s a serious fault, missing board, or it’s not actually the B750 being sold.

That’s worth chasing because the B750 is a respected late-70s/early-80s integrated: solid power, good phono stage, and the sort of clean, authoritative presentation Revox did well. At this price, the upside is obvious—great sound for very little outlay, and even a service can still leave you well ahead; just confirm it powers up, both channels play cleanly, controls aren’t wildly noisy, and the input selector/function switching is behaving, since age-related switch and capacitor issues are the main things to check.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Revox

Revox traces its origins to 1948 in Herisau, Switzerland, when Willi Studer founded his company as a workshop for electronic equipment, initially producing high-voltage oscilloscopes and early reel-to-reel tape machines under the Dynavox name. By 1951, Studer launched the first Revox-branded recorder, the T26, marking the brand's entry into premium consumer audio while reserving the Studer name for professional studio gear. This Swiss precision engineering heritage propelled Revox through decades of innovation, from the iconic A77 tape deck in 1977—paired with matching amplifiers, tuners, and turntables—to speaker development starting with the AX series in the 1970s, all designed to deliver studio-grade fidelity to discerning home listeners.

The brand's product focus centered on high-end analog playback, excelling in reel-to-reel tape recorders like the legendary A77 and B77, which became staples for audiophiles. Revox expanded into complete hi-fi systems, including integrated amplifiers, FM tuners, turntables sourced from partners like Thorens, and loudspeakers manufactured in their Black Forest facilities. While digital components like DACs and modern streaming gear emerged later, the core legacy remains in meticulously engineered tape machines and matched system components that prioritized sonic purity over mass-market appeal.

Today, Revox holds a revered position as a high-end vintage icon and collector's favorite, synonymous with uncompromising Swiss build quality and studio-derived performance. Though separated from Studer in 1994, the brand endures as a niche boutique force, recently reviving reel-to-reel production in 2016 with partners like Horch House, appealing to purists who value heritage engineering in an era of digital convenience.
