CHASSIS REMOVAL is accomplishe

13、d by first removing the COMBO or HEADs cabinets back panel. Then remove the four (4) screws from the top of the cabinet that secure the chassis. Disconnect the ” speaker plug from the speaker jack (COMBO only). Then slide the chassis toward the rear of the cabinet. 2. MAIN PCB REMOVAL is accomplishe

14、d by re- moving the IEC Connector, the fuse holder, the speaker jack nut, the line out jack nut and the two screws that hold the chassis rear panel to the chassis. Remove the rear panel and the va- cuum tubes. Disconnect the ribbon cable that goes between the main PCB and the uDSP PCB. Remove all sc

15、rews holding the main PCB to the stand offs on the chassis. Then remove the front panel knobs and the nuts holding the controls to the front panel. Slide the front panel PCB back away from the front panel. Remove all the fast-ons connecting the main PCB to the power indicator, the power transformer

16、and the output transformer. Now the main PCB can be lifted up and out of the chassis taking advan- tage of the slots in the back of the chassis. 3. The COMBO and the HEAD share the same chassis and circuitry. The combo contains a captive 10” speaker while the head can be used with any suitable speak

18、T DESCRIPTION This section provides concise information about new or unusual circuitry designs incorporated into this amplifier model. The purpose is to aid the ser- vice technician by providing insight into the design areas most likely to become obstacles in trouble- shooting. Information is focuse

19、d for its effective use while maintaining the security of Fender proprie- tary information whenever possible. MAIN PCB The Main PCB Assy. contains the circuitry for the pre-amplifier, the power amplifier, and the power supply. The controls are located on a breakaway section of the main PCB with ribb

20、on cables con- necting them. PRE-AMPLIFIER Op-amp U6-A provides the high impedance instru- ment input with 14db of gain. Op-amp U6-B is configured as an active filter producing high fre- quency pre-emphasis. U1-A provides another 20db of gain. Its output is clamped to +/-2V. The uDSP PCB Assy. choos

21、es either the low gain output from U6-B or the higher gain output from U1-A depend- ing on the amplitude of the guitar input signal. Op- amp U3-A is configured as a differential input amp recovering the signal after uDSP processing and conversion back to an analog signal. The LOUT and SUPER CHAMP X2

22、 COMBO/HEAD (This is the model name for warranty claims) 5 ROUT signals are the input to the differential amp which acts as a three pole active low pass filter for de-emphasis. The output of U3-A is applied to a buffer amp U1-A which drives op-amp U1-B which provides the LINE OUT signal and the powe

23、r amp input. FET Q-1 provides system muting during power up/down in conjunction with the power sense circuits composed of D9, Q2, and Q4. USER INTERFACE The 4 16 position encoders (S2 S3) for the VOICE and EFFECT SELECT are sent to the GPIO buss of the uDSP and polled at a 1000Hz rate. The 6 potenti

24、ometers CH1 VOLUME (R85), CH2 VOLUME (R83), CH2 GAIN (R84), TREBLE (R82), BASS (R81), and AND FX LEVEL (R80) generate DC Voltages (0.0V to +3.3V) that are polled at a 1000Hz rate by the uDSPs A/D converter. POWER AMPLIFIER The power amplifier consists of V1, V2, and V3. T2 and associated circuitry.

25、The signal is fed to the gate of V1-B in common cathode configuration. The signal is then fed from the plate of V1-B to the gate of V1-A which is operating as a phase splitter driv- ing V2 from its plate and V3 from its cathode. V2 and V3 are operating in Class A-B push-pull mode. T2 matches the imp

26、edance of V2s plate to the 8 Ohm speaker. Negative feedback is provided by R23 feeding signal back to V1-Bs cathode. DSP PCB The DSP PCB is located in the back of the chassis opposite the power transformer. It provides the am- plifier voicing and effects functions. The DSP PCB is not field serviceab

27、le and must be replaced as an assembly. USB PCB The USB PCB provides the USB interface to the DSP and ESD protection. The USB interface is used to communicate between the users computer for the purpose of altering the amps presets or res- toring the amp to factory settings. POWER SUPPLY T1 has four

28、secondary windings for the +5V regula- tor, the +/-12V supplies, the tube filaments and the high voltage supply. The violet winding is rectified by a fullwave bridge, filtered by C41 and fed to the DSP PCB where it is regulated to +3.3VDC and fed back on to the main PCB. Similarly, the center tapped

29、 orange and yellow winding is rectified, fil- tered and fed to +/-12V zeners to provide power to the operational amplifiers and other circuitry. The red windings provide the high voltage for the va- cuum tubes. The green winding provides 6.3VAC for the vacuum tube filaments. A voltage doubler is emp

30、loyed to produce -41.9VDC to bias the output tubes, V2 and V3. . SUPER CHAMP X2 COMBO/HEAD (This is the model name for warranty claims) * Non-serviceable part. Replace complete parent assembly.
