Simply put, the wiring: the power supply consists of three wires

VCC+ GND VEE-

The voltage cannot exceed+-34V

It is recommended to be within 30V. direct

The blue socket contains the Input signal+-

OUT+is connected to the positive pole of the speaker

The speaker negative is connected to the GND of the power board

 

There are three tubes on the board, including two high-power tubes and one medium power tube. They must all be installed on the same radiator to play the role of temperature compensation.
