Power Output: 250 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 0.5% at
250 watts, below .04% at 1 watt. Approximate actual power available at “clipping” 270 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) 5Hz to 70kHz.
Frequency Response: (-3dB points at 1 watt) 0.5Hz to 110 kHz.
Input Sensitivity: 2.4V RMS Balanced for rated output. (25.5 dB gain into 8 ohms.)
Input Impedance: 200K ohms Balanced.
Output Taps: 4, 8, 16 ohms.
Output Regulation: Approximately 0.9dB 16 ohm load to open circuit (Damping factor approximately 10).
Overall Negative Feedback: 8.8dB.
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 Storage: Approximately 900 joules.
Power Requirements: 105-130VAC 60Hz (260-250VAC 50Hz) 770 watts at rated output, 1000 watts maximum, 380
watts at “idle,” 1 watt off.
Tube Complement: 3 Matched pair KT120 (Power output V1-6); 1 Matched pair KT120 (Driver V8-9); 2 6H30 (Gain
stage V7 and Regulator Driver V10); 1 6550C (Regulator V11).
Dimensions: Width 19" (48.3 cm)
Height 8.75" (22.2 cm)
Depth 19.5" (49.5 cm)
Handles extend 1.5" (3.8 cm) forward.
Weight: 73 lbs. (33.2 kg) Net; 88 lbs. (40 kg) Shipping.
