Power output: 75 watts per channel continuous from20Hz to 20kHz. 1kHz total harmonic Distortion typically 0.6% at 75 watts, below 0.05% at 1 watt. Approximate actual power available at ‘clipping’ 76 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) 7Hz to 60kHz
Frequency response: (-3dB points at 1 watt) 0.7Hz to 75 kHz
Input sensitivity: 1.4V RMS BAL for rated output. (25 dB Bal Gain into 8 ohms.)
Input impedance: 300K ohms Balanced.
Output Polarity: Non-inverting. Balanced input pin 2+ (IEC-268)
Output taps: 8 ohms, 4 ohms
Output regulation: Approximately 1.0dB 8 ohm load to open circuit (Damping factor approximately 8)
Overall negative feedback: 15dB
Slew rate: 10 volts/microsecond
Rise time: 4.0 microseconds
Hum & noise: Less than 0.06mV RMS – 112dB below rated output (IHF weighted, input shorted)
Power supply energy storage: Approximately 520 joules
Power requirements: 105-125VAC 60Hz (210-250VAC 50Hz) 410 watts at rated output, 500 watts maximum, 230 watts idle
Tubes required: 2 – Matched pair KT150 – Power output; 2 – 6H30 Driver
