This sounds like the variable resistor that sets the audio level is out of 
adjustment. This resistor is located at the left rear corner of the master 
circuit board (when looking towards the front of the player) and is labeled 
R4127 on the diagram on the inside cover of the player and R27 on the actual 
circuit board. The player needs to be placed in the service position to adjust 
this resistor, so I wouldn't recommend adjusting this without having a service 
manual and following its guidelines and step-by-step procedures. Rotating the 
knob on the resistor clockwise increases the gain of an operational amplifier 
inside the audio demodulator integrated circuit and permits the audio output 
level to be adjusted over a wide range.

The SJT100 is a monaural player, so this unit is probably an SJT200 that was 
either mislabeled, or had its cover swapped with an SJT100. There should be a 
label inside the player to the left of the turntable that can be compared to 
the label on the back of the player cover.
