Stereo integrated valve amplifier with KT150s, single-ended class A.
TRV-A150XR: the design
The TRV-A150XR uses one KT150 per channel in single-ended class A: 18 W per channel, enough to drive speakers of different kinds.
Bias is set from the top plate with the meter. The supply has a large toroidal transformer and silicon-carbide Schottky diodes. The aluminium remote, an MM phono input and a headphone output are standard.
