Usher R-1.5 Power Amplifier

The R-1.5 amplifier is designed to drive all speakers to produce a warm-toned "vacuum tube" sound quality. The use of high-quality components, including metal film resistors and film capacitors, enhances Arthur's reputation in high-quality manufacturing. High-power bipolar transistors designed by Motorola can meet complex power and current requirements. Its large-scale AC power transformer can be used in conjunction with a high-capacitance filter system to obtain the purest sound. Other features include Burrow-Brown OPA2134P Sound Plus series arithmetic optimized amplifiers, bridge switches for mono function operation, banana plugs and direct-lock bare wire terminals, as well as additional optional balanced inputs and on the front and rear panels. Large handle.
