PRODUCT DETAILS

Technical Specifications

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 the 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.

Physical Specifications

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- 4 matched pair KT150 (Power output V1-4); 4 6H30 (Gain stage V5 and V6).
