Volume control, left and right??

Volume control for Dragon's Lair is *not* clear in the manual. This is all the information that I have been able to find.

There are "LEFT" and "RIGHT" volume potentiometers. These potentiometers only control the volume of the LaserDisc sound. Dragon's Lair does not provide volume control for the "beeps" and "buzz" sounds.

Where the hell are these sound potentiometers located in the sound circuit?
They are in series between the LaserDisc player and the DL main pcb.

Dragon's Lair sound is *not* true stereo. It is *normal* for music/sound effects to come out one channel and the attract mode announcer and Daphne's voice to come out of the other.
