Audio Research VS60 Tube Power Amplifier (used)
Very nice condition ARC VS60, Made in USA of course, 4 x 6550 power tubes, 2 x 6H30 for input. 8 and 4 Ohm taps. The original manual and biasing tool is included, also the original tube damper rings. Ser.#70004501. I don't have the original box but will pack it safe for shipping. This amp is quiet, dynamic and musical. It'll drive nearly any speaker.
• 50 watts per channel of tube power
• newer EH power tubes, ~50-100 hrs
• new Nichicon filter caps in the power supply
• Sovtek 6H30's (the EH Gold would make a great upgrade)
No sales tax. Shipping in Canada is included. For US shipping please contact us.

POWER OUTPUT
50 watts minimum continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at 50 watts, below .05% at 1 watt. Approximate actual power available at "clipping": 52 watts (1kHz) (Note that the actual RMS power output is dependent upon both line voltage and "condition" ie: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)
FREQUENCY RESPONSE
(-3dB points at 1 watt) 1.0Hz to 70 kHz.
INPUT SENSITIVITY
1.0V RMS Single-ended for rated output. (26dB gain into 8 ohms.)
INPUT IMPEDANCE
100K ohms Single-ended.
OUTPUT TAPS
8 ohms, 4 ohms
HUM & NOISE
Less than 0.2mV RMS - 100dB beow rated output (IHF weighted, input shorted).
POWER SUPPLY ENERGY STORAGE
Approximately 166 joules.
POWER REQUIREMENTS
105-125VAC 60 Hz (210-250VAC 50Hz) 320 watts at rated output, 500 watts maximum, 200 watts at "idle".
