Audio Research "USED" Reference 75 Amplifier in mint condition with new Audio Research tested KT120 vacuum tubes and brand new LED kit .
The REF75 is Audio Research Corp.’s power amplifier introduced as the gateway into their prestigious Reference lineup.
Indeed all ARC power amps are push-pull fully balanced designs wherein all stages—input, gain/drive and output—are fully balanced. The manufacturer’s propensity for such balanced circuits which are inherently resistant to symmetrical distortion is manifested in the XLR inputs exclusively. Another characteristic is that the binding posts only accept spade lugs and bare wire. The normally open ends for banana plugs are clogged with non-removable gold pins. Finally the mains socket is designed for 20A-rated plugs which are beefier than the standard 16A kind and as such probably a bit of excess.
According to the manufacturer, the REF75 is housed in an enclosure reminiscent of ARC’s older classic designs. The front sports two illuminated analog power/bias meters, one per channel. The meters are rectangular to remind us of days gone by. Below each meter is a knob to select between power output and bias monitor display mode. The outer dimensions of the REF75 are the same as for the REF150 amp. The front panel, handles and top cover are available in black or clear anodized.
