Triode Corporation was founded by its President Mr. Jun-ichi Yamazaki in Koshigaya Saitama in the year 1994. It started as a small business in his garage with the goal of creating a very high-quality Audio Amplifier products that can be sold worldwide at affordable price, targeting tube lovers that only wants real music and nothing else. After a few years, Triode began to attract attention from all over the world and expanded its lineup of tube electronics that include very high-quality models. Triode has about 20 models of tube amplifiers and are well known for its high-quality sound and reliability.
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.
