Amplifier

Power output: 155 watts per channel continuous from20Hz to 20kHz. 1kHz total harmonic Distortion typically 0.6% at 155 watts, below 0.03% at 1 watt.Approximate actual power available at ‘clipping’ 160 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 80kHz
Frequency response: (-3dB points at 1 watt) 0.5Hz to 120 kHz
Input sensitivity: 2.0V RMS BAL for rated output. (24 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
Overall negative feedback: 14dB
Slew rate: 13 volts/microsecond
Rise time: 2.0 microseconds
Hum & noise: Less than 0.1mV RMS – 114dB below rated output (IHF weighted, input shorted).Controls: Rotary selector for tube bias, Power on/off, fan speed, auto shut-off on/defeat, RS232, 12V trigger
Power supply energy storage: Approximately 1040 joules
Power requirements: 105-125VAC 60Hz (210-250VAC 50Hz) 730 watts at rated output, 900 watts maximum, 420 watts idle
Tubes required: 4 – Matched pair KT150 – Power output; 4 – 6H30 Driver
