Audio Research Reference 750

The Reference 750 delivers over 750 watts of power into speaker loads of 4 to 16 ohms. This is achieved by the use of massive, custom-built power and output transformer delivering current from sixteen KT150 vacuum tubes in each channel. Thanks to 48 hours of burn-in, followed by thorough testing and careful matching of tubes, the amplifier requires little maintenance. Power supply regulation is also achieved by 6550WE and 6H30 vacuum tubes. Tube bias is controlled by two KT150 tubes, each driving a bank of eight KT150 output tubes.
