Commentary
Stereo pre-main amplifier using V-FET.
All stages are directly connected pure complimentary service SEPPOCL circuit and DC-amplifier configuration using four Nch and Pch V-FETs.
An equalizer stage with two LEC transistor and V-FET for small signal is adopted.
The flat amplifier uses a DC amplifier that extends the band to DC in order to achieve faithful waveform transmission.
Equipped with a muting switch.
