Our Thoughts RADAR AI

When new, the SC22 cost roughly £37 10s; at £415, this is right on the supplied used-market median, so the price is fair rather than a bargain. It is also comfortably below the upper quartile of £1,459, though the wide spread shows that condition, servicing and completeness matter greatly.

This is a well-regarded vintage control unit, offering a characterful valve-stage presentation, useful tone controls, filtering and a proper phono input. The crucial question is whether this is the standard SC22, which needs the matching Radford amplifier’s HT/LT supply via its umbilical, or the self-powered SC22P; the former is not a standalone preamp. Check that cable, controls, phono section and power-amplifier compatibility are present and working. At £415, a clean, tested example is a sensible buy for a Radford system, but an untested unit deserves negotiation.

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

About Radford

Radford Electronics, a storied British hi-fi brand from Bristol, traces its origins to 1946 when radio enthusiast Arthur Hedley Radford—amateur callsign G6YA—began crafting amplifiers in the postwar era. The company quickly gained traction with its debut hi-fi model in 1959, building on pre-war electronics expertise to produce gear that captured the imagination of early audiophiles. Though the original firm wound down, its legacy endures through Radford Revival, a UK craft outfit meticulously recreating classics with modern tweaks while honoring exacting original specs.

Radford's product focus centered on amplifiers, where they excelled in both valve (tube) and early transistor designs, including integrated models like the HD250. They pioneered transmission line speakers and dabbled in preamps, such as the rare SC22P with onboard power supply. Output transformers stood out as their hallmark, delivering unparalleled clarity and power. Turntables, DACs, headphones, and cables never featured prominently; their domain was pure amplification and speaker innovation.

Renowned for quality "second to none," Radford occupies a niche vintage-collector space, appealing to high-end enthusiasts chasing that golden-era British sound. Once a benchmark for Williamson-style amps, today's Revival editions cater to boutique buyers seeking authentic tone with reliability upgrades, cementing their status among obscure icons rather than mass-market players.
