Audio Research V 70 Power Amp

Selling my vintage Audio Research V70 power amp. Fully balanced power amp equipped with eight KT-90 tubes. The KT-90 output tubes are Ei's made in Yugoslavia.  These tubes are something special.  They regularly sell for around $180 a matched pair.  The driver tubes are vintage General Electric.  This amp has all the benefits of a tube amp but with the tenacity of a solid state amp. It is warm and lucid. Especially good on vocals and small ensemble recordings. 60W per channel output. Best paired with mid-size and larger monitor speakers.  I am the original owner of this amp.  It was recently serviced, and just rechecked by the local Audio Research authorized repair facility.  In perfect working order.   Cosmetically, the amp is in good condition considering its age.  I have done my best to take care of the amp. Probably a little dust inside the tube cage.  I have the original double box and can ship the amp securely in this original box.  I have the owner's manual also   Paypal adds 3%.  I Will also accept personal checks (after it clears), money orders or a cashier's check.   Local pickup or delivery preferred.  For a buyer who purchases the amp at my asking price, I will ship the amp within the continental US via Fedex ground at no additional cost, i.e. free shipping within the continental US.

Here are the amp's specifications from Audio Research:

Power output 60
watts minimum continuous at 16 ohms from 15Hz to 20kHz with less than
1.0% total harmonic distortion (typically below .005% at 1 watt).
Approximate actual power available at "clipping": 62 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.) Power bandwidth (-3dB points) 12Hz to 40kHz
Frequency response - Input sensitivity 1.1V RMS balanced for rated output
Input impedance 400K ohms balanced Output taps - Output regulation Approximately 0.3dB 16 ohms load to open circuit
Overall negative feedback 20dB
Damping factor Approximately 30
Distortion - Slew rate 20V/µs
Rise time 2.0 µs
Hum & noise Less than 1.0mV RMS - 90dB below rated output (20kHz bandwidth unweighted, inputs shorted)
Power supply energy storage Approximately 280 joules
Power requirements 105-125VAC 60Hz (210-250VAC 50Hz) 500 watts at rated output, 700 watts maximum, 370 watts at "idle"
Tube complement (4 matched pairs) KT90 power output, (4) 6FQ7/6CG7 drivers
Dimensions 19"
(48 cm) W (standard rack panel) x 7" (18 cm) H x 15 ¾" (40 cm) D (front
panel back). Handles extend 1 ⅝" (4.1 cm) forward of the front panel.
Output connectors extend 1" behind rear panel.
