Audio Research VT 80SE

You are looking at the Audio Research VT80 SE Stereo Amplifier with the KT150 Kit!

This amplifier is in mint condition. I purchased it directly from ARC about 3 years ago. The Tubes have plenty of life left in them! I am upgrading my speakers and (sadly) require more power than the VT80 SE can deliver.

This is an amazing-sounding amplifier, full of warmth and depth.

Buyer pays shipping and insurance.

Specs:

POWER OUTPUT

75 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at 75 watts, below 0.05% 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 very critical.)



POWER BANDWIDTH

(-3dB points) 7Hz to 60kHz.

FREQUENCY RESPONSE

(-3dB points at 1 watt) 0.7Hz to 80kHz.

INPUT SENSITIVITY

1.4V RMS BAL for rated output. (25dB Bal gain into 8 ohms.)

INPUT IMPEDANCE

300K ohms Balanced (150K ohms SE)

OUTPUT POLARITY

Non-inverting. Balanced input pin 2+ (IEC-268)

OUTPUT TAPS

8 ohms, 4 ohms

OUTPUT REGULATION

Approximately 1.0dB 8 OHM LOAD TO OPEN CIRCUIT (Damping factor approximately 8)

OVERALL NEGATIVE FEEDBACK

15dB

SLEW RATE

10 volts/microsecond

RISE TIME

4.0 microseconds

CHANNEL SEPARATION

112dB
