SEPP-ITL--ITL-OTL system circuit directly connected to all stages to achieve high output with low distortion factor.
An ICZ-stage direct-coupled circuit is also used for the phono amplifier.

Four tape decks can be connected at the same time, and a microphone jack with level control, muting switch, bus treble control, high / low cut, and loudness switch are installed.

Built-in power transistor protection circuit allows single use of pre-main and main.
