Specifications

  • POWER OUTPUT: 210 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 0.5% at 210 watts, below .02% at 1 watt.Approximate actual power available at “clipping” 240 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) 10Hz to 150kHz.
  • FREQUENCY RESPONSE: (-3dB points at 1 watt) 0.5Hz to 240 kHz.
  • INPUT SENSITIVITY: 1.7V RMS Balanced for rated output (27 dB gain into 8 ohms.)
  • INPUT IMPEDANCE: 200K ohms Balanced.
  • OUTPUT TAPS: 4, 8, 16 ohms.
  • OUTPUT REGULATION: Approximately 0.6dB 16 ohm load to open circuit (Damping factor approximately 14).
  • OVERALL NEGATIVE FEEDBACK: 12dB.
  • SLEW RATE: 40 volts/microsecond.
  • RISE TIME: 1.2 microseconds.
  • HUM & NOISE: Less than 0.3mV RMS – 106dB below rated output (IHF-A weighted, input shorted, 16 ohm output). 
  • POWER SUPPLY ENERGY STORAGE: Approximately 787 joules.
  • POWER REQUIREMENTS: 105-130VAC 60Hz (260-250VAC 50Hz) 680 watts at rated output, 950 watts maximum, 380 watts at “idle,”.15 watts off.
  • TUBES REQUIRED: 3 – Matched pair 6550C (Power output V1-6); 1– Matched pair 6550C (Driver V8-9); 2– 6N1P (Gain stage V7 and Regulator Driver V10); 1 6550C (Regulator V11).
  • DIMENSIONS : 19" (48.3 cm) W x 8.75" (22.2 cm) H x 19.5"(49.5 cm) D. Handles extend 1.5" (3.8 cm) forward.
  • WEIGHT: 74 lbs. (33.6 kg) Net; 89 lbs. (40.4 kg) Shipping.
