Commentary
Tube type monaural power amplifier with push-pull configuration using triode 2A3.
A pure 2A3 triode is used, and residual noise of less than 0.5 mV is realized by selective use of 2A3 and improvement of the hum balancer circuit.
Sufficient drive voltage is obtained by using an interstage transformer.
