Audio Research Reference 160 mono tube power amplifier
140 watts continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at
140 watts, below 0.04% at 1 watt. (Note that actual power output is dependent upon
both line voltage and “condition” i.e.: if power line has high distortion, maximum power
will be affected adversely, although from a listening standpoint this is not critical).
(-3dB Points) 5Hz to 70kHz.
(-3dB points at 1 watt) 0.5Hz to 110kHz.
2.4V RMS Balanced for rated output. (25.5 dB gain into 8 ohms).
200 k ohms Balanced.
Non-inverting. Balanced input pin 2+ (IEC-268).
16 ohms, 8 ohms, 4 ohms.
Approximately 0.6dB 16 OHM LOAD TO OPEN CIRCUIT (Damping factor

14dB SLEW RATE: 13 volts/microsecond RISE TIME: 2.0 microseconds.
105-130VAC 60Hz (210-250VAC 50Hz) 400 watts at rated output, 700 watts maximum,
260 watts at “idle”, 1 watt off.
2 matched pair KT150 (Power output V1-4); 2 6H30 (Gain stage V5 and V6).
