Stereo power amplifier which made the performance of
monophonic power amplifier No20L condense.
The RF noise includeded on AC
line, and the high-pass filter and anti buzz circuitry for the measure against
an asymmetrical current are adopted as the power-source part of a right-and-left
independency. Moreover, the toroidal transformer which is proud of rated 1200VA
is carried in the transformer by the right-and-left independency.
A mass filter capacitor and a power transistor are directly linked with an output stage by an oxygen-free-high-conductivity-copper bus bar, and also the purity of the power source is polished by adoption of the triple it1 by a quality capacitor.
In a voltage amplification cartridge and the driver stage, the two-step
differential cascode circuitry and the stabilizing supply were adopted, and the
output stage is always controlled by first class operation.
input is also supported.
Bridge connection is possible and a using is
possible also as monophonic amplifier.
