POWER OUTPUT : 140 watts continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at 140 watts, below 0.04% 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 critical).
POWER BANDWIDTH : (-3dB Points) 5Hz to 70kHz.
FREQUENCY RESPONSE : (-3dB points at 1 watt) 0.5Hz to 110kHz.
INPUT SENSITIVITY : 2.4V RMS Balanced for rated output. (25.5 dB gain into 8 ohms).
INPUT IMPEDANCE : 300k ohms Balanced; 100k ohms Single-ended.
OUTPUT POLARITY : Non-inverting. Balanced input pin 2+ (IEC-268).
OUTPUT TAPS : 16 ohms, 8 ohms, 4 ohms.
OUTPUT REGULATION : Approximately 0.6dB 16 OHM LOAD TO OPEN CIRCUIT (Damping factor approximately 14).
OVERALL NEGATIVE FEEDBACK : 14dB SLEW RATE: 13 volts/microsecond RISE TIME: 2.0 microseconds.
POWER REQUIREMENTS : 105-130VAC 60Hz (210-250VAC 50Hz) 400 watts at rated output, 700 watts maximum, 260 watts at “idle”, 1 watt off.
TUBES REQUIRED : 2 matched pair KT150 (Power output V1-4); 2 6H30 (Gain stage V5 and V6).
DIMENSIONS : Width 19.0” (48.26 cm) x Height 10.25” (26 cm) x Depth 21.5” (54,61 cm)
With Handles and Connectors: 20.75” (52.7 cm)
WEIGHT : 100lbs
