Nikko TRM-800

The TRM-800 was a high-end solid state integrated stereo amplifier made in Japan, using NEC power transistors, by Nikko.

It was the top-of-the-line model in the Nikko amplifier range of TRM's series; housed in a wooden walnut-finished cabinet and a brushed aluminum front panel, was introduced in 1975[1] the same year as the Marantz 2235.

[2][3] It was a two-channel amp;[1] however, it had three sets of speaker connections; those powered selected by buttons.

At 8 ohms, the amp could put out 65 Watts per channel RMS (90 Watts per channel RMS at 4 ohms[1]), delivering superb high fidelity sound with exceptional tone quality.

The amp has internal circuit breakers which prevent it from clipping or overheating.
