Nikko Gamma 2

Tested and Cleaned
At USD399, this Nikko Gamma 1/2 FM tuner listing feels ambitious for a 1978 rack-mount unit, especially without clear condition details. Solid examples in good cosmetic and working order typically trade in the USD200-350 range on enthusiast forums, with beat-up or unserviced ones dipping under USD200. Unless it's pristine with recent recap and mods, you're paying a premium—haggle hard or walk if photos show rack rash or faded meters.
Buyers, prioritize a full function test: verify stereo separation, quieting on weak signals, and dial cord tension, as these analog beasts suffer from dried capacitors and sticky mechanisms after 45 years. Insist on the original power cord and any rack ears if included; skip if no service history, since SAW filter failures can kill FM pull without a tech rebuild.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Nikko Audio emerged from Nikko Electric Industry Co., founded in 1933 in Kanagawa, Japan, initially as a manufacturer of fuses and electrical equipment for the national railroad. Post-World War II, the company expanded into communications technology, entering the hi-fi market in the late 1960s through the influence of an audiophile family member with exceptional hearing. This Japanese heritage fueled a brief but notable run of precision-engineered audio components before the brand shuttered its audio division amid the 1990s market downturn.
The brand focused primarily on amplifiers, producing standout series like the Alpha line of power amps from the late 1970s and early 1980s, and the high-end TRM series, including the 1975 TRM-800 integrated stereo amplifier with its robust 65 watts per channel output, NEC power transistors, and stability down to 4 ohms. Tuners such as the FAM-600 and compact hi-fi gear rounded out their compact-form-factor offerings, emphasizing clean circuit design and no-frills power over expansive categories like speakers, turntables, or modern digital components.
Today, Nikko holds a cherished position among vintage collectors, prized for its build quality and dynamic sound that rivals contemporaries from more prominent Japanese marques. Though limited in distribution during its era, these components endure as attainable high-fidelity treasures, evoking the golden age of Japanese amplification engineering.
