POWER two-way toggle switch powers the 2204 on and off. With the toggle switch in the DOWN ("ON") position, the 2204 is
on. In the UP position, the 2204 is OFF.
STANDBY applies high voltage to the vacuum tube anodes (and screen grids) during use of the 2204. To ensure long tube life,
first power the unit on with the STANDBY toggle switch in UP position for approximately 30 seconds. You can then switch to
DOWN ("ON") to use the 2204. With the toggle switch in the UP position, the 2204 is in STANDBY mode. In the DOWN
position, the 2204 is in OPERATE mode
