VS115VS115 Vacuum Tube Stereo Power Amplifier from Audio Research revisits the classic look of the VS110 with its open architecture and natural anodized top plate – now more ventilated for better heat dissipation. Drawing upon the successful REF110 input stage design, the VS115 uses a FET input with two 6H30 triodes in each channel for gain and as a cathode follower-driver for the 6550C-equipped output stage. This allows both balanced and single-ended connections in a true differential topology yielding a much wider power bandwidth (110kHz in contrast to 40kHz for the VS110). There is a new power transformer, and power output from the four matched pair of 6650C output tubes is 120WPC, providing excellent drive and control. Bias test points for each output tube are located on the rear panel, along with a 12V trigger which allows remote turn-on. A heavy 20-amp IEC detachable cord conducts the A.C. supply.
