CHASSIS REMOVAL is accomplished by first removing two (2) screws from the cabinet side panel and four (4) screws from the top of the cabinet; disconnect the ” speaker plug(s) from the speaker jack(s) and then slide the chassis toward the rear of the cabinet. 2. uDSP PCB ASSEMBLY REMOVAL is accom- plished by disconnecting the ribbon cable on the PCB Assembly, releasing the tabs on each of the plastic stand-offs which the PCB assem- bly is mounted. Removal of the uDSP PCB assembly may be necessary should any of the Digital Effects operate improperly. 3. STAGE 100/160 DSP MAIN PCB REMOVAL is accomplished by removing the following items: All knobs including washers and nuts (14) , one (1) input jack nut and washer, (1) screw near mains fuse, seven (7) screws at the heatsink attached from the bottom of the chassis. Dis- connect the transformer and primary leads at P1-P14. Disconnect the breakaway PCB rib- bon cable at P20 and speaker wires (blk/wht) at P15-P16. Disconnect the ribbon cable to uDSP assembly at P19. Remove the power LED from the jewel assembly. 4. STAGE 100/160 DSP BREAKAWAY PCB RE- MOVAL is accomplished by removing five (5) nuts and washers at the jacks and two (2) screws at the XLR jack. Disconnect the ribbon cable from the main PCB at P20 and the speaker wires (blk/wht) at P15-P16. PCB EXCHANGE POLICY Parts marked with a single asterisk (*) in the Part Lists (starting on page 10) are not field replaceable. If a failure due to one of these components is de- tected, please contact the Fender Dealer Customer Service Department to order the com- plete PCB Assembly. STAGE 100/160 DSP (This is the model name for warranty claims) 5 CIRCUIT DESCRIPTION This section provides an overview of any new or unusual circuitry incorporated into this amplifier model. The purpose is to aid the service technician by providing insight into the design areas most likely to present a challenge in troubleshooting. This overview is focused for the efficient use and security of Fender proprietary information. PRE-AMPLIFIER The guitar input signal is fed into the high pass filter at U1A before splitting into two signal paths. The normal channel signal path (U1B to U3B) is ac- tive until FETs Q2, Q4, and Q6 are turned on activating the drive channel signal path (U2A to U3B). Turning on FETs Q1, Q3, and Q5 activates the “More Drive” channel signal path for increased gain and sustain. Differential amp U8A and fol- lower U8B adjust the signal level and provides +1.65VDC bias voltage to the uDSP effects card. The preamp is in series with the digital effects card, therefore, disconnecting the card breaks the overall signal path. The low pass filter at U5B recovers the signal from the uDSP card and sends it to the external effects loop and power amplifier. POWER AMPLIFIER “Flying Rail” power amp topology. The output stage is referenced to ground, and the output signal is de- rived from the center tap of the high voltage power supply (C86 & C87) which is floating. Diffamp U7 B amplifies voltage developed at the load sense re- sistors (R120123) to provide negative current feedback. Inserting an 8 load at Ext. Spkr (J7) turns on FET Q20 creating an attenuation network (R117119) to compensate for the increased cur- rent at 4 total load impedance. This allows the amplifier to have a similar frequency response run- ning either an 8 or 4 speaker load. Thermistor RT2 monitors the heatsink temperature. Its resistance increases with temperature and at approx. 100 C turns on xstr Q23. This shorts out C77, turning on FET Q22 providing a muting func- tion at the power amp input. The amplifier remains muted until the heatsink cools down, at which point, normal operation is restored. POWER SUPPLY Standard bridge rectifiers for both high and low voltage sections, with zener regulation (D5253) for the +/16V supplies. Halfwave rectifier (D4647, C48) supplies U11, 7805 regulator for +5V supply for the uDSP card and digital userinterface. DIGITAL USER INTERFACE The uDSP effects card generates clock signals HD0 (45Hz) and HD1 (90Hz) which control the 4053 CMOS switch to read pots R134, R135, and R138. The DC level (05V) of the pots controls the reverb level, fx level, and fx time/rate. Power (+3.3V) is switched to encoders S4 and S5 via the 4053, also controlled by HD0. The outputs of the 4bit encod- ers, isolated by diodes D28D35, determine the active reverb and fx algorithms (HD4HD7). DIGITAL NOISE The uDSP effects card generates some high fre- quency noise (50kHz), which is a normal product of DSP processing. This noise is not audible and does not effect amplifier performance, but may be visible when observing the output of the amplifier on an oscilloscope. .
