Solid state pre-main amplifier with all stages directly connected by OCL circuit.
OCL circuit is used in the main amplifier section.
In this circuit, the capacitor used in the signal circuit has been eliminated. In addition, by adopting a two power supply system, the capacitor of the speaker output circuit has been eliminated and all stages are directly connected to each other to improve the sound quality.
A differential amplifier is used in the first stage to improve DC stability and linearity.
All of the preamp sections use low-noise PNP silicon transistors to eliminate noise and noise problems.
It is equipped with a protection circuit, detects when the load is short-circuited, and limits the current flowing to the power transistor. It is also an instantaneous recovery type, and when the load is short-circuited, it returns to normal status.
This circuit is independent of the left and right channels.
Equipped with a program indicator.
Uses a slide control system.
The preamp section and main amplifier section can be used separately.
