This is the main power switch. CF-080LS is designed to be left in POWER ON position at all times. In
POWER ON position, volume control circuit is active, and vacuum tube gain stage is in STANDBY

main power switch to OFF position, and unplug AC cable from AC outlet.
[STANDBY/OPERATION Switch]
This switch turns vacuum tube gain stage into STANDBY (OFF) or OPERATION (ON) mode. In
STANDBY position, power supply to vacuum tube section is turned OFF.
When this switch is in OPERATION position, vacuum tube gain section is turned ON. MUTE is in effect
