Stereo integrated valve amplifier with 300Bs, single-ended class A.
TRV-A300XR: the design
The TRV-A300XR is a single-ended class A amplifier built around the 300B triode, in the simplest configuration.
Bias is fixed: the meter, the adjustment and the hum balance sit on the top plate, so changing valves is within anyone's reach. Toroidal transformer and silicon-carbide Schottky diodes in the supply; MM phono input and volume remote as standard.
