New, this was a substantial late-1970s Sony integrated amplifier; today, £313 sits just above the £302 median for seven recent comparable listings, and comfortably within the normal market band of £292–£326. That makes it a fair asking price rather than a bargain, with value depending heavily on condition and whether it has been properly tested or serviced.
The TA-3650 is a capable, well-built 55-watt-per-channel amplifier with a good phono stage, useful pre-out/power-in connections, and the solid, tactile feel typical of Sony’s better 1970s equipment. It remains an attractive choice for vintage-system duty and should drive a broad range of speakers confidently. Because it is direct-coupled and now nearly 50 years old, confirm clean operation, low hum, reliable protection engagement, and absence of channel dropouts; evidence of recapping or competent servicing would make £313 considerably easier to justify.

Sony emerged from the ruins of post-World War II Japan, founded on May 7, 1946, by Masaru Ibuka and Akio Morita as Tokyo Tsushin Kogyo K.K. in Tokyo's Nihonbashi district. Starting with radio repairs and Japan's first magnetic tape recorder, the duo secured transistor licensing from Bell Labs, pioneering the TR-55 transistor radio in 1955. Renamed Sony Corporation in 1958—from the Latin "sonus" for sound—the brand symbolized Japan's ascent from cheap imitations to innovative leadership, fueled by Ibuka's engineering prowess and Morita's global marketing vision.
Sony's hi-fi legacy spans headphones, amplifiers, speakers, turntables, and DACs, alongside landmark formats like the Compact Disc in 1982 and Blu-ray. Iconic products include the Walkman for portable audio revolution and Trinitron televisions, blending consumer accessibility with cutting-edge tech. Today, offerings like the Signature Series headphones and ES amplifiers target discerning listeners seeking refined soundstaging and dynamic range.
Positioned as a mid-to-high-end powerhouse, Sony commands respect among knowledgeable buyers for blending mass-market reliability with premium performance, outpacing many pure audiophile brands in innovation and value. Far from vintage relic or niche boutique, it dominates with forward-thinking engineering, holding strong market share in headphones and streaming ecosystems.
