POWER OUTPUT  – 75 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at 75 watts, below 0.05% at 1 watt. (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 80kHz.
INPUT SENSITIVITY – 1.4V RMS BAL for rated output. (25dB Bal gain into 8 ohms.)
INPUT IMPEDANCE – 300K ohms Balanced (150K ohms SE)
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
CHANNEL SEPARATION – 112dB
HUM & NOISE – –84dBV weighted, 8 ohms tap
SIGNAL TO NOISE – 112dB
CONTROLS – Power on/off, auto shut-off on/defeat, Input BAL/SE, RS232, 12V trigger
AMBIENT AIR TEMPERATURE – 30° C (86° F) maximum ambient air temperature
POWER SUPPLY ENERGY STORAGE – Approximately 350 joules
POWER REQUIREMENTS – 100-125VAC 60Hz (200-250VAC 50Hz) 410 watts at rated output, 500 watts maximum, 230 watts idle. Sleep power < 1 watt
TUBES REQUIRED – 2 – Matched pair KT150 – Power Output; 2 – 6H30 Driver
