REAR PANEL FUNCTIONS A.C. ACCESSORY OUTLET (120 V AC, 60 Hz) (Load limit 200 Watts) This socket is provided as a convenience outlet for any A.C. accessory. GROUND SWITCH Gives player control of polarity. Positions ''A" and '-B" ground to each side of the line respectively. The "OFF" position disconnects all but the third line chassis ground. Try each position to find minimum hum condition. FUSE 21/2 Amp 125 Volts Slo-Blo CAUTION: Disconnect amplifier A.C. plug from outlet before changing fuse. Remove fuse by pressing in and unscrewing cap counter-clockwise. Replace only with Littlefuse No. 31302.5 or Bussman fuse No. MDL 2.5. ON / OFF SWITCH Turns amplifier on and off. STANDBY SWITCH Allows tube filaments to remain heated during standby periods. Amplification is instantly available without warm-up time. No danger of unwanted sound when in quiet periods. SPEAKER JACK Connects speakers to amplifier. EXTENSION SPEAKER JACK Provides a connection to an extension speaker enclosure. OUTPUT LINE/RECORDING JACK Permits direct connection to recorders, P.A. systems or amplifiers, with input impedances of 200 ohms or more. This control makes it unnecessary to use matched power output tubes for optimum performance. Best balance is obtained by setting the "MASTER VOLUME" to "1" and adjusting for minimum hum level. Ordinarily, no adjustment should be required unless the output tubes are changed. VIBRATO AND REVERB JACKS (4) Plug-in connections to pedal and to reverb unit. HUM BALANCE After the "GROUND SWITCH" has been positioned to minimum hum, the hum balance may be used to further reduce hum. This control should not need adjustment unless tubes or other components are changed. CORRECTIVE CHECK LIST If your amp is set up but does not function, check the following items: - Is the amp power supply cable plugged into an electrical outlet? • Is there power at the outlet where the amp is plugged in? • Is the speaker plugged into the amplifier speaker jack? • Are all the control knobs tumed up above 4? • Is the volume control on your instrument turned up? - Is the fuse good? If, after checking all of the above, the system is still not performing correctly, consult your Fender Service Dealer. CARE OF VINYL COVERING If the vinyl covering and handles require cleaning, use a mild soap and warm water solution, wipe with a damp cloth, and buff dry with a terry cloth. This will restore the original luster. REPLACEMENT PARTS Under the terms of the limited warranty, defective parts will be replaced by your authorized Fender dealer. Fender Original Equipment tubes are designed and built to provide optimum performance in musical instrument amplifiers. To maintain best performance and quiet operation, replacement should be made with original equipment tubes. Fender Musical Instruments furnishes warranty service through authorized Fender dealers.
