Other Notes: "The SD135 is an entirely new amplifier for Audio Research involving a new mix of discrete devices within the framework of a pure analog, solid-state design.

Like the larger HD220, the new SD135 ("SD" for "Silicon Drive") uses Thermal Trak® self-biasing output devices in a Class A-B design. And like the HD220, it accommodates either single-ended or balanced inputs. But unlike the larger hybrid, the SD135 features an all-solid-state input stage using multiple JFET devices in each channel, directly driving the output stage – no interstage coupling capacitors needed. Because expensive coupling capacitors and high voltage regulated supplies required in tube circuits can be omitted, the SD135 is within reach of many more music-lovers." - Audio Research
