A classic, highly regarded valve amp, and this one lands right on the money. At £818, it sits exactly at the median of recent comparable listings, with the market running from £756 at the 25th percentile to £868 at the 75th, so this is a fair price rather than a bargain or an ambitiously priced ask.
What makes it worth a look is the Stereo 20’s reputation for a big, open, musically natural sound from a relatively compact push-pull EL84 design, with strong appeal for efficient speakers and vintage-leaning systems. If the unit is genuinely clean and properly serviced, the upside is in owning a desirable, easy-to-love classic that’s always liquid on the used market; at this level, I’d mainly want confirmation of service history, output transformer health, and whether it’s running stock or upgraded parts.

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.
