Troubleshooting during phono input of stereo turntable
Since this unit is not provided with an earth terminal, the hum noise may be increased during playback when it is connected to a
record player having an earth lead separated from a RCA lead.
In such a case, replace the screw shown in the following figure with XJBSD30P10000 and connect the earth lead of the player.
(Replace the black screw with a general un painted screw.)
