*US* BUYERS IGNORE MESSAGE ABOVE SAYING THERE IS TARIFFS FOR THE BUYER THAT IS NOT TRUE! I PREPAY ALL US BUYER TARIFFS NO TARIFFS FOR YOU TO PAY, YOU PAY IS ONLY AT CHECKOUT NO HIDDEN FEES*The Nikko NA-40 Integrated Amplifier & NT-40 AM FM Stereo Tuner is a rare and valuable addition to any home audio setup. This amplifier, part of the Nikko brand, is capable of delivering high-quality sound and comes with AM and FM radio inputs for added versatility. The model number NA40 signifies a specific design within the line of Nikko audio equipment, known for its performance and reliability. Ideal for music lovers looking to enhance their listening experience, this integrated amplifier and tuner combo is a must-have for those seeking a seamless audio solution.
At US$136, this sits just above the typical market center of US$133 and a touch over the US$134 75th percentile, so it reads as fair-to-slightly-ambitious rather than a bargain. It’s close enough to the norm that a clean, working example can still make sense, but there isn’t much pricing slack here.
The NT-40 is the kind of straightforward integrated amp that appeals to buyers who want an unfussy, competent vintage piece with real hi-fi credibility. If the cosmetics are honest and the controls are quiet, the value is in getting a well-regarded, listenable amp without chasing rarities or paying collector money. At this price, I’d want proof of healthy operation, since the upside is in condition more than in the number itself.

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.
