(image for) Call for Price

For Sale: Tested and working classic 1980's Japanese stereo components for the discriminating listener.

Excellent sound quality- no hum, static, or distortion. Very little wear plus nice and clean. Florescent power level meters on amp working (can't really see them in the video because of bright lights). All controls working correctly- looks like the power light and the tuner indicator light are out, otherwise working 100%, no issues. The tuner is also in quite nice shape except for a little cosmetic wear on top of case. Gets excellent FM stereo reception even with just short piece of copper wire for an antenna. AM tested good too. Tuning lights, stereo indicator light, and station memories tested and working correctly.

Silverface Nikko amp and Onkyo tuner match up quite nicely as seen in photos and video. Click link to see video of the set collaborating live:

Nikko NA-2090 Integrated Amplifier

Distinctive performance in power supplies and output stages makes the NA-2090 a most desirable unit for the serious audiophile.

Operation is by self-illuminated buttons which work under the slightest pressure. An 11-LED power level indicator for each channel expands and contracts according to the power output moment to moment. Switching distortion is absolutely zero, thanks to the use of the latest non-switching amplifier in the power amp section. Power output is 85 watts per channel, minimum RMS, both channels driven, into 8 ohms from 20 to 20,000 Hz with no more than 0.015% THD.

The power amp is of DC configuration for high quality reproduction and improved sonic transparency. Not a single capacitor is used in the amp's signal path or NFB network. Virtues include controlled damping, uniform phase response in mid-to-high frequencies, near total lack of Transient Intermodulation distortion. A built-in pre-preamp for moving coil cartridges can be switched via a front panel control.
