Kenwood Power Supply

Fig. 4 shows the front face of the main power supply (Kenwood). The tracking is turned on (positive and negative supplies have the same settings). The supply voltage is +/- 12V and the current is limited to 0.15 A. The output protect should be turned on to limit the current if something goes wrong. The output has to be turned on with the Output button on the upper right. The red light over the button will turn on. The power supply has a bridge that connects the common and ground terminals on the output, which has been disconnected lately.
