The TRV-A300 XR is a Class A single amplifier that brings out the attractiveness of 300 B simply. Although it is a fixed bias method, it has a meter for checking the bias on the top surface, a bias adjustment volume, and a ham balance volume, so you can easily make the optimum adjustment even when changing the vacuum tube. In this unit, Sic Schottky barrier rectifier diode is adopted as a rectifier circuit, and combined with a toroidal power transformer constitute a power supply circuit with excellent efficiency and excellent response. Phono equalizer circuit (MM type correspondence), remote controller for volume adjustment are also equipped as standard. Finished as one standard that will become Triad’s standard.
