Specifications
POWER OUTPUT:
750 watts per channel continuous from
20Hz to 20kHz. 1kHz total harmonic distortion typically
0.5% at 750 watts, below .04% at 1 watt. Approximate
actual power available at “clipping” 850 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) 15Hz to 150kHz.
FREQUENCY RESPONSE:
(-3dB points at 1 watt) 1 Hz to 200
kHz.
INPUT SENSITIVITY:
4.6V RMS Balanced for rated output.
(24 dB gain into 8 ohms.)
INPUT IMPEDANCE:
200K ohms Balanced.
OUTPUT TAPS:
4, 8, 16 ohms.
OUTPUT REGULATION:
Approximately 0.5dB 16 ohm load
to open circuit (Damping factor approximately 17).
OVERALL NEGATIVE FEEDBACK:
13dB.
SLEW RATE:
20 volts/microsecond.
RISE TIME:
1.5 microseconds.
HUM & NOISE:
Less than 0.2mV RMS – 110dB below rated
output (IHF-A weighted, input shorted, 16 ohm output).
POWER SUPPLY ENERGY STORAGE:
Approximately 1300
joules.
POWER REQUIREMENTS:
105-130VAC 60Hz (200-270VAC
50Hz) 2100 watts at rated output, 2400 watts maximum,
800 watts at “idle”.
TUBES REQUIRED:
8 Matched pair KT120 Power Output; 1
6550WE Regulator; 1 6H30 Regulator Amplifier; 1
matched pair KT120 Driver; 1 6H30 follower.
DIMENSIONS:
13.5" (34.3 cm) W x 23" (58.4 cm) H x 20.8"
(52.8 cm) D. Handles extend 1.5" (3.8 cm) forward and
rearward.
WEIGHT:
170 lbs. (77.2 kg) Net; 395 lbs. (180 kg) per pair
shipped weight.
