Leak Stereo 20 Vintage Valve Amp Serviced with Volume Control Very nice. 220-240 V Only.
£1,000 is ambitious for a Stereo 20 even in good cosmetic condition; it sits well above the sort of used value these usually trade at when they’re simply described as working or recently serviced. A fully recap’d example was being discussed at £600, which makes £1,000 feel like top-end money unless this one has unusually strong provenance, an exceptional service history, or a proper recent rebuild by a known specialist.
That said, the Stereo 20 remains a highly regarded little EL84 push-pull amp: sweet midband, fine timing, and enough power for efficient speakers while keeping the classic Leak character intact. If it’s genuinely tidy, original where it matters, and electrically healthy, it can still be a rewarding buy—but at this price I’d want proof of recent work, quiet operation, and matched output valves before calling it easy money.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Founded in 1934 by Harold Joseph Leak in London, England, LEAK emerged as a pioneering force in British hi-fi, initially crafting public address systems and cinema amplifiers before pivoting to high-fidelity home audio amid post-war innovation. With engineer Ted Ashley's contributions, the brand rode the 1950s hi-fi boom, producing landmark valve amplifiers like the TL/12 series, which set benchmarks for low distortion and performance, establishing LEAK as a global leader in affordable excellence.
LEAK specialized in integrated amplifiers, such as the iconic Stereo 20, Stereo 30, and Stereo 50, alongside innovative loudspeakers featuring the patented "Sandwich" foam-core drivers for precise bass and clarity. The lineup extended to radio tuners, pickups, tonearms, and turntables, blending valve warmth with emerging transistor tech to dominate the stereo era.
Acquired by the Rank Organisation in 1969 and dormant by the late 1970s amid Japanese competition, LEAK's revival under the IAG Group since 2020 honors its heritage with modern classics like the Stereo 130 and 230 integrated amplifiers, plus CD transports and streamers. Revered by vintage collectors for cult models like the Stereo 30, it holds mid-tier prestige today—delivering high-end British sound at accessible prices for discerning buyers seeking timeless refinement.
