About the Reference 80S
The Audio Research Corporation Reference 80S is a fully balanced, differential stereo tube power amplifier using four KT150 output tubes and two 6H30 dual-triode gain-stage tubes. It offers switchable Ultralinear/pentode and Triode operating modes, rated at 70 watts per channel in Ultralinear mode and approximately 33 watts per channel in Triode mode. Connectivity includes balanced XLR and single-ended RCA inputs, with selectable 4-, 8-, and 16-ohm speaker output taps. Its features include auto-bias, output-tube monitoring with an operating-hour meter, a variable-speed cooling fan, RS-232 control, and a 12V trigger. The official Audio Research product page and documentation remain available, but the Reference 80S appears to be an older/currently archived model rather than an actively promoted current product. No definitive manufacturer discontinuation notice was found.
