Audio Research Reference 750 SE:

SPECIFICATIONS:

Power output: 750 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic Distortion typically 0.5% at 750 watts, below .04% at 1 watt. Approximate actual power available at « clipping » 850 watts (1kHz). (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 very critical.)
Power bandwidth: (-3dB points) 15Hz to 150kHz
Frequency response: (-3dB points at 1 watt) 1 Hz to 200 kHz
Input sensitivity: 4.6V RMS Balanced for rated output. (24 dB Gain into 8 ohms.)
Input impedance: 200K ohms Balanced
Output taps: 4, 8, 16 ohms
Output regulation: Approximately 0.5dB 16 ohm load to open circuit (Damping factor approximately 17)
Overall negative feedback: 13dB
Slew rate: 20 volts/microsecond
Rise time: 1.5 microseconds
Hum & noise: Less than 0.2mV RMS – 110dB below rated output (IHF-A weighted, input shorted, 16 ohm output)
Power supply energy storageApproximately 1300 joules
Power requirements: 105-130VAC 60Hz (260-750VAC 50Hz) 2100 watts at rated output, 2400 watts maximum, 800 watts at « idle »
Tubes required: 8 Matched pair KT150 Power output; 1 6550WE Regulator; 1 6H30 Regulator Amplifier; 1 matched pair KT150 Driver; 1 6H30 follower
