Commentary
All-silicon transistor integrated amplifier for warm tone.
The tone control uses the same method as PAT-4 and PAS-3X. At the midpoint position, the circuit is removed and the amplifier becomes a complete flat amplifier.
The mode selector switches between three levels : stereo, blend, and mono.
In addition, the Blend Position can be used for Dynaco 4-channel system, Dynaco 3D system, or when using headphones to bring more realistic feeling.
Two speaker outputs are installed.
The special input is wired for the 2nd phono, and the cartridge similar to the phono circuit can be used.
