Commentary
A stereo power amplifier using a beam type output tube.
The beam-type output tube 5881/6L6GC is used for ultra linear connection.
The output stage is self-biased to stabilize its operation and is designed to be less susceptible to aging.
Twin triode 6CS7 is used for first stage amplification and phase inversion. The first stage is SRPP and the phase inversion is Mulard type.
Damper tube 6CG3 is used for the rectifier circuit.
The 6CG3 is a damper tube of 350 mA, which does not apply high voltage at once and greatly contributes to the life of the output tube.
The output transformer is equipped with a customized energy audio transformer tuned for RS-35a.
Hood and spare pipe are included.
