You are exactly right Zmix, it has a cap switch across the hot and neutral.
Do the grounds shown refer to a chassis ground or just a reference to the circuit ground? |
Both, the circuit ground will be tied to the chassis, usually through the input jacks.
The A.C. leakage through the cap on the ground switch is what gives you a nasty shock when the ground switch is in the 'wrong' position and you touch another amp or a microphone...
