User manual FENDER D AQUISTO

[. . . ] It is suggested that you read this manual thoroughly to understand all the features and functions of your new amplifier. WARNING: TO REDUCE THE RISK OF FIRE OR SHOCK HAZARD, DO NOT EXPOSE AMPLIFIER TO RAIN OR MOISTURE. A "CUSTOM" VIBRASONIC REAR PANEL FUNCTIONS A. FUSE - The fuse is in the AC supply of the amplifier and will help to protect the amplifier and operator in the event of an electrical fault. If a fuse blows, it should only be replaced with a fuse in accordance with the listing at the fuse holder. [. . . ] If the amplifier repeatedly blows fuses, it should be checked out by a qualified technician. UNDER NO CIRCUMSTANCES should a fuse of a different type, higher current rating, or a fuse bypass be used, as this could damage the equipment and present a serious safety hazard. In the STANDBY position, the amplifier is off; however, power is applied to the tube filaments so as to eliminate warm-up time. Use of this feature during short breaks versus using the POWER SWITCH will increase tube life. This jack is wired in parallel with the MAIN SPEAKER JACK, and must only be used in conjunction with the MAIN SPEAKER JACK. Should the EXTERNAL SPEAKER JACK be used without also using the MAIN SPEAKER JACK, there will be no sound. Note that the amplifier is optimized for a 4 ohm speaker load, and that the 15" speaker in the cabinet is 4 ohms. Should a total load of more or less than 4 ohms be used, the amplifier will not put out its maximum power output before distortion occurs. The footswitch allows you to turn the VIBRATO and REVERB features on and off without having to operate the controls on the front panel. Note that only the REVERB feature will operate without plugging in the footswitch. F. C. D. "CUSTOM" VIBRASONIC FRONT PANEL FUNCTIONS A, B. Turning the control full counter-clockwise turns the VIBRATO feature off. The VIBRATO feature can also be turned on and off using the footswitch. R. PILOT LAMP - When the lamp is illuminated, the "CUSTOM" VIBRASONIC is receiving power. Should the lamp burn out, turn the power off, unscrew the red jewel and replace the lamp with a type T47 light bulb. "CUSTOM" VIBRASONIC FOOTSWITCH FUNCTIONS A. VIBRATO SWITCH - Push on, push off switch that turns the VIBRATO feature on and off. B. REVERB SWITCH - Push on, push off switch that turns the REVERB feature on and off. VR IE BV ADJUSTMENTS HUM BALANCE ADJUSTMENT - This adjustment minimizes hum heard at the speakers. It is set at the factory, and needs to be adjusted only if any of the smaller tubes, especially one of the 12AX7As, are replaced. To make hum adjustment: with nothing plugged into the amplifier, rotate the STEEL channel volume, middle, and bass controls full clockwise. Rotate the GUITAR channel treble control, and all the STEEL channel controls full counter-clockwise. Insert a slotted screwdriver into the HUM BALANCE CONTROL (located on the bottom of the chassis) and rotate it back and forth until you find the null (setting of minimum hum). If you have any questions, consult your authorized Fender Service Center. [. . . ] If you have any questions, consult your authorized Fender Service Center. Should the bias need adjusting, it should be performed by your authorized Fender Service Center.
