AUDIO RESEARCH GS150 TUBE TYPE POWER AMPLIFIER OUR STORE DISPLAY UNIT. Box and manual. Blemish free. Here is the url for the GS150 page on the Audio Research website: http://www.audioresearch.com/en-us/products/power-amplifiers/gs150 "Audio Research’s GS150 might have some styling cues from yesteryear that could have you thinking its sound will be old-school as well, but I didn’t find that to be the case. It’s a thoroughly modern-sounding amplifier that passes music along with high accuracy, completely devoid of the kinds of colorations heard from more traditional tubed designs. Although the GS150’s lack of such colorations might not be the cup of tea of those who, like our own Jason Thorpe, live for the old-time tube sound, its adeptness at re-creating recorded space will probably win them back. For those who want a neutral sound, excellent resolution, high power, ease of use (for a tubed amp), superb build quality, and beautiful industrial design, Audio Research’s GS150 is very tough to beat." . . . Doug Schneider das@soundstagenetwork.com POWER OUTPUT 155 watts per channel continuous from20Hz to 20kHz. 1kHz total harmonic distortion typically 0.6% at 155 watts, below 0.03% at 1 watt.Approximate actual power available at ‘clipping’ 160 watts (1kHz). (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 very critical.) POWER BANDWIDTH (-3dB points) 5Hz to 80kHz. FREQUENCY RESPONSE (-3dB points at 1 watt) 0.5Hz to 120 kHz. INPUT SENSITIVITY 2.0V RMS BAL for rated output. (24 dB Bal gain into 8 ohms.) INPUT IMPEDANCE 300K ohms Balanced. OUTPUT POLARITY Non-inverting. Balanced input pin 2+ (IEC-268). OUTPUT TAPS 8 ohms, 4 ohms. OVERALL NEGATIVE FEEDBACK 14dB. SLEW RATE 13 volts/microsecond. RISE TIME 2.0 microseconds. HUM & NOISE Less than 0.1mV RMS – 114dB below rated output (IHF weighted, input shorted).Controls: Rotary selector for tube bias, Power on/off, fan speed, auto shut-off on/defeat, RS232, 12V trigger POWER SUPPLY ENERGY STORAGE Approximately 1040 joules. POWER REQUIREMENTS 105-125VAC 60Hz (210-250VAC 50Hz) 730 watts at rated output, 900 watts maximum, 420 watts idle. TUBES REQUIRED 4 – Matched pair KT150 – Power Output; 4 – 6H30 Driver.
