This is a seller’s market at US$250: that sits above the US$200 75th percentile and well over the US$189 median, so it’s a bit ambitious rather than a bargain. For a clean, tested example it’s not absurd, but buyers should expect to negotiate unless the unit is especially well documented or freshly serviced.
The Beta II is a respected vintage preamp with flexible phono capability and a genuinely capable line stage, so the appeal is real for vinyl-first systems. Value goes up fast if it’s original, quiet, and complete with the right knobs/covers/manuals; the main buyer concern is age-related servicing, especially switches, controls, and phono performance, which matter more at this price than cosmetic wear.
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.
