Should this bulb burn out, unscrew the red jewel and replace the lamp with a type T47 light bulb. VC IH BA I DUAL PROFESSIONAL REAR PANEL FUNCTIONS J A. FUSE - The fuse is in the AC supply of the amplifier and will help to protect the amplifier in the event of an electrical fault or tube failure. If a fuse blows, it should only be replaced by one with the same type and rating. NEVER use a fuse of higher current rating as this could damage the equipment and present a serious safety hazard. If the amplifier repeatedly blows fuses, it should be checked out by an authorized Fender service center. In the STANDBY position, the amplifier is off, although power is applied to the tube filaments to keep them warmed up and ready to play. A good rule of thumb is to turn the power switch on and wait at least 50 seconds before turning on the standby switch. This jack MUST only be used in conjunction with the main SPEAKER JACK (Item D). If the EXTERNAL SPEAKER JACK is used without a cord plugged into the main SPEAKER JACK , there will be no sound. [. . . ] Check under all tube covers to see that the tube filaments are glowing a dull orange. If, after checking all of the above, the system is not performing correctly, consult your Fender authorized service center.
