POWER OUTPUT: 50 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at 50 watts, below .05% at 1 watt. Approximate actual power available at "clipping" 52 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) 12Hz to 90kHz.

FREQUENCY RESPONSE: (-3dB points at 1 watt) 1.0 Hz to 100 kHz.

INPUT SENSITIVITY: 0.5V RMS Single-ended for rated output. (32 dB gain into 8 ohms.)

INPUT IMPEDANCE: 50K ohms Single-ended.


MAXIMUM INPUT: 3.5V RMS (any input). Optional 6dB pad for CD use.

OUTPUT POLARITY: Non-inverting (any input).

OUTPUT REGULATION: Approximately 1.5 dB 8 ohm load to open circuit (Damping factor approximately 5).

MONO SUBWOOFER OUTPUT: 1V RMS at rated power.

OVERALL NEGATIVE FEEDBACK: 10dB.

SLEW RATE: 10 volts/microsecond.

RISE TIME: 2 microseconds.

HUM & NOISE: Less than 0.14mV RMS - 103dB below rated output (IHF weighted, input shorted).
POWER SUPPLIES: Electronically regulated Low and High Voltage supplies for input stages. Automatic 30 second warm-up/brown-out mute.

POWER SUPPLY ENERGY STORAGE: Approximately 166 joules.

POWER REQUIREMENTS: 100-125VAC 60Hz (200-250VAC 50Hz) 320 watts at rated output, 500 watts maximum, 205 watts at "idle". 0.5 watts power off.

TUBES REQUIRED: (2 ) Matched pair 6550EH - Power Output; (3) 6N1P input and driver.

DIMENSIONS : 14"(35.6 cm) W x 8"(20.3 cm) H x 16"(40.6 cm) D. Rear connectors extend .88" beyond chassis.

WEIGHT: 34 lbs. (15.5 kg) Net; 40 lbs. (18.2 kg) Shipping.
