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 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 4, 8, 16 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 4 matched pair KT150 (Power output V1-4); 4 6H30 (Gain stage V5 and V6) Dimensions Width 19.0” (48.26 cm) Height 10.25” (26 cm) Depth 21.5” (54,61 cm) With Handles and Connectors: 24” (60.96 cm) Weight 100lbs
