Amplificatore integrato Audio Research I 50 Usato pari al nuovo

Kit di valvole appena sostituito con valvole originali . Lavoro eseguito da Audio Natali. Imballo originale

Power Output: 50 watts continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% per channel, below 0.1% 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 critical)

Power Bandwidth: (-3dB points) 10Hz to 22kHz

Frequency Response: (-3dB points at 1 watt) 7Hz to 30kHz

Input Sensitivity: 1.25V RMS for rated output.

Input Impedance: 100K ohms Balanced, 48K ohms Single Ended
