Commentary

Vacuum tube stereo power amplifier with output stage pure A-class operation.

The circuit configuration uses three parallel EL84 output vacuum tubes (six single channels) for ultra-linear operation.
In addition, the use of an independent power supply circuit for left and right channels and an automatic bias system for each output tube further improves physical characteristics and operation stability.
