The age matters: this is a 1968–71 solid-state design, not a current-generation amplifier, and the later Delta 70 was its successor. At £261, it is clearly above the 75th-percentile comparable asking price of £216, versus a median of £160, so the listing looks ambitious rather than a bargain.
It remains an appealing classic: 35 watts per channel, a useful built-in MM phono stage, straightforward controls, and the punchy, clean presentation that makes these early Leak transistors worthwhile. But at this money, condition and servicing need to be unusually convincing. Original capacitors, tired switches, noisy controls, and ageing output-stage components are realistic concerns on a 50-plus-year-old example. Unless it has documented restoration, excellent cosmetics, and confirmed fault-free operation, a buyer should negotiate toward the £160–£216 region.
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.
