determines transformer-coupled or direct output operation. The
setting of this switch controls which amplifier output terminals are
active and what type of filter shape will be used for the bass control.

selector switch.

accidental changes in switch position.To set the lock, loosen the screw
opposite the desired switch position. Slide the lock under the loosened
screw and align it with the switch.Tighten the screw making sure the
lock has not shifted.
