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) 875 watts at rated output, 700 watts in Triode mode, 500 watts at “idle”, 3.6 watts off
TUBES REQUIRED
