Here's a closer look at the volume switch mounted on its own sub-assembly that is attached to the circuit board by two screws. To the left of the switch itself, you can see the end of the tubular electrolytic condensor with the red wire running from it to the switch. The Sawafuji mica condensor is the brown rectangular part just above the switch. Above that is another Sawafuji mica condensor, (the part that looks like a brown domino with colored spots).
