HORN - PRODUCTS :: STEREO :: LAMP AMPLIFIERS

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