  • Technische specificaties

    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)

    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

    Tubes Required: 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 (WxDxH): 48.3×49.5×22.2 cm. Handles extend 3.8 cm forward.

    Weight: 33.2 kg
