Commentary
This is a stereo power amplifier developed for expansion to multi-channel and 3D systems.
The circuit is composed of all-silicon transistors and uses a quasi-output circuit. The complimentary service stage uses the SEPPOTL method.
An emitter-follower circuit is inserted in front of the six transistors that constitute the power amplifier circuit.
This keeps the input impedance high and prevents the distortion factor from deteriorating.
It has a unique structure without a protection circuit.
It has a volume for input level set.
Newly developed LUXMAN's original speaker terminal is used.
The front panel is made of aluminum material with hairline processing and is finished with white gold alumite dyeing.
