A PAIR (2) OF AUDIO RESEARCH REFERENCE 600 MONOBLOCK VACUUM TUBE POWER AMPLIFIER. One of the biggest and finest Tube Amplifiers ever build; those Huge Monoblocks can deliver Enormous energy to any load. All Tubes (around 64 if I'm not wrong) were replaced a couple of years ago, and total time after replacement is less than 30 hours. Tubes were imported from Tube Depot USA (see pictures). Description: Using all vacuum-tube input and driver stage circuitry in conjunction with 16 type 6550C output tubes, each amplifier puts out up to 600 watts of wide-bandwidth (12 Hz to 80 kHz) power into speaker impedances of one to 16 ohms.Measured frequency response (-3 dB points) is 2 Hz to 200 kHz. Main power supply energy storage is rated at 669 joules.
Output terminals are proprietary gold-plated 5-way binding posts. Each output tube is individually biasable from the front panel. Monitoring, real-time power output and tube biasing data. Variable control of meter illumination and internal cooling-fan speed is standard.
A standby mode limits tube current draw during warmup or between periods of operation. Front panels of both Reference Series models are available in anodized natural aluminum. 500 watts continuous at 16 ohms from 20Hz to 20kHz with less than 1% total harmonic distortion typically less than. Typical power under average circumstances will be around 550 watts. Maximum power under ideal conditions will be around 600 watts.
(-3dB points) 12Hz to 80kHz. (-3dB points at 1 watt) 2Hz to 200 kHz. 2.0V RMS balanced for rated output. Approximately 0.5dB 16 ohm load to open circuit. 105125VAC 60Hz (210250VAC 50Hz) 1600 watts at rated output, 2200 watts maximum, 800 watts at idle, 300 watts standby.REFERENCE 600: (8 matched pairs) 6550C power output; (4) 6550C regulators; (2) 7233 regulators; (2) 6922 regulator amplifier; (8)12AX7 driver; (2) 6922 input.
