Nikko TRM-800

The TRM-800 was a solid state integrated stereo amplifier made in Japan, using NEC power transistors, by Nikko. Beautifully housed in a wooden walnut-finished cabinet, was introduced in 1975, the same year as the Marantz 2235. It was a 2 channel amp; 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). Unlike many amps of this time, however; the TRM-800 was stable at lower impedances than 8 ohms; down to four ohms. The TRM-800's frequency response ranges 10Hz to 40.000 Hz ±1 dB with T.H.D. less than 0.1% at rated output.Its preamplifier and main amplifier were separable for multi-channel amplifier systems. The amp has internal circuit breakers which prevent it from clipping or overheating. Its power consumption is 250 watts. For equalization it has only a bass and a treble knob; however the frequency of these are selectable; between 250 and 500 Hertz for the bass, and between 2.5 and 5 kHz for the treble. It also has a high, low, and a subsonic filter.
