Triode TRV-A300XR Valve Integrated Amplifier

The TRV - A 300 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. I finished it as one standard that will become Triad's standard.
