Description
MSRP: $25,000 for the pair Used, mint condition Uses IEC C19 power cables (Included) Including extra set of tubes. Ships in original box. Will ship individually (two separate packages) @ 90 lbs each, totaling 180 lbs. Since any listing 150 lbs and above is required by eBay to be classified as freight, and these will not be shipped freight, the initial shipping price is not accurate. Please DO NOT PAY without receiving an accurate quote from us. Manual: https://audioresearch.com/wp-content/uploads/2021/08/REF250_Manual.pdf Specifications: POWER OUTPUT: 250 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 0.5% at 250 watts, below .04% at 1 watt. Approximate actual power available at “clipping” 270 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 70kHz. FREQUENCY RESPONSE: (-3dB points at 1 watt) 0.5Hz to 110 kHz. INPUT SENSITIVITY: 2.4V RMS Balanced for rated output. (25.5 dB gain into 8 ohms.) INPUT IMPEDANCE: 200K ohms Balanced. OUTPUT TAPS: 4, 8, 16 ohms. OUTPUT REGULATION: Approximately 0.9dB 16 ohm load to open circuit (Damping factor approximately 10). OVERALL NEGATIVE FEEDBACK: 8.8dB. SLEW RATE: 20 volts/microsecond. RISE TIME: 1.5 microseconds. HUM & NOISE: Less than 0.2mV RMS – 110dB below rated output (IHF-A weighted, input shorted, 16 ohm output). POWER SUPPLY ENERGY STORAGE: Approximately 900 joules. POWER REQUIREMENTS: 105-130VAC 60Hz (260- 250VAC 50Hz) 770 watts at rated output, 1000 watts maximum, 380 watts at “idle,” 1 watt off. TUBES REQUIRED: 3 Matched pair KT120 (Power output V1-6); 1 Matched pair KT120 (Driver V8- 9); 2 6H30 (Gain stage V7 and Regulator Driver V10); 1 6550C (Regulator V11).

Description
MSRP: $25,000 for the pair Used, mint condition Uses IEC C19 power cables (Included) Ships in original box. Will ship individually (two separate packages) @ 90 lbs each, totaling 180 lbs. Since any listing 150 lbs and above is required by eBay to be classified as freight, and these will not be shipped freight, the initial shipping price is not accurate. Please DO NOT PAY without receiving an accurate quote from us. Manual: https://audioresearch.com/wp-content/uploads/2021/08/REF250_Manual.pdf Specifications: POWER OUTPUT: 250 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 0.5% at 250 watts, below .04% at 1 watt. Approximate actual power available at “clipping” 270 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.)
