Specifications.
-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)
-POWER BANDWIDTH: (-3dB points) 12Hz to 50kHz.
-FREQUENCY RESPONSE: (-3dB points at 1 watt) 1.0 Hz to 60 kHz.
-INPUT SENSITIVITY: 1.1V RMS Single-ended for rated output. (25 dB gain into 8 ohms.)
-INPUT IMPEDANCE: 100K ohms Single-ended.
-OUTPUT TAPS: 8 ohms, 4 ohms.
-OUTPUT REGULATION: Approximately 1.0 dB 8 ohm load to open circuit (Damping factor approximately 10).
-OVERALL NEGATIVE FEEDBACK: 12.5dB.
-SLEW RATE: 5 volts/microsecond.
-RISE TIME: 5 microseconds.
-HUM & NOISE: Less than 0.2mV RMS - 100dB below rated output (IHF weighted, input shorted).
-POWER SUPPLY ENERGY STORAGE: Approximately 166 joules.
-POWER REQUIREMENTS: 105-125VAC 60Hz (210-250VAC 50Hz) 320 watts at rated output, 500 watts -maximum, 200 watts at "idle".
-TUBES REQUIRED: (2 ) Matched pair 6550EH - Power Output; (3) 6N1P input and driver.
-DIMENSIONS : 14" (35.6 cm) W x 7" (17.8 cm) H x 14" (35.6 cm) D. Rear connectors extend .88" beyond chassis.
-WEIGHT: 32 lbs. (14.5 kg) Net; 38 lbs. (17.3 kg)
