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.
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
47 lbs. (21.3 kg) Net; 63 lbs. (28.6 kg) Shipping.
