11、 from the Rear Cabi- net Panel and two (2) screws from the top of the Cabinet; detach the speaker wires from the speaker 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 uDSP PCB Assembly, releasing the

12、tabs on each of the plastic Stand-offs which the uDSP PCB Assembly is mounted. Removal of the uDSP PCB Assembly may be necessary should any of the Digital Effects operate improperly. 3.BULLET 15 DSP MAIN PCB REMOVAL is ac- complished by removing the following items: All Knobs, one (1) screw at the C

13、D Input Jack, two (2) nuts and washers at the Input and Head- phone Jacks, two (2) screws at the Heatsink which attaches to the Chassis. Desolder the Transformer Leads at P1, P4, P5, P6 and P7. Disconnect the Yellow and Black wires at the Power Switch leading from P2 and P3. Discon- nect the Ribbon

14、Cable at P8. PCB EXCHANGE POLICY Parts marked with a single asterisk (*) in the Part Lists (starting on page 9) 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. BUL

15、LET 15 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 cha

16、llenge 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 U1B before splitting into two signal paths. The Normal Channel signal path (U1A to U3B) is ac- tive unti

17、l the Drive Select switch is pushed “IN” to change the signal path from the Normal Channel to the Drive Channel (U2B to U3B). Differential amplifier U4A and follower U4B adjust the signal level and provides +1.65VDC bias voltage to the uDSP effects card. The preamp is in series with the digital effe

18、cts card, therefore, disconnecting the card breaks the overall signal path. The signal from the uDSP card is recovered at U6A. It is neces- sary to bring the signal back to its level prior to entering the uDSP card. This is accomplished by increasing the signal gain at U6B. The signal is fed through

19、 the Passive Tone Control circuitry to the summing amplifier at U3A, where it is mixed with the CD/Tape Input. The signal is fed through the Headphone buffer amplifier (U8A and U8B) and on to the Power Amplifier. FET Q2 is used to mute U6A at power shutdown, preventing any uDSP card signal transient

20、s from getting through to the Power amplifier. POWER AMPLIFIER Current Feedback topology is used for the Power amplifier. The Power amplifier IC (U5) is configured as a non-inverting amplifier. Diodes D7 and D8 are used for common-mode protection of the amplifier. Current feedback is achieved by sam

21、pling current at the negative speaker terminal and feeding the signal back to the inverting node of the Power am- plifier through R41 and series capacitor C25. The negative speaker terminal is referenced to ground through resistors R42 and R43. FET Q1 provides a mute function at the Power amplifier

22、input. POWER SUPPLY Standard bridge rectifiers for high voltage (+/-22V), with zener regulation (D1415) for the +/15V sup- plies. +15V supplies U7, 7805 regulator for +5V supply for the uDSP card and digital userinterface. DIGITAL USER INTERFACE The uDSP Effects control (R65) is a linear pot that se

23、ts a DC level (05V), which is read by an A/D converter located on the uDSP card. These DC levels determine which desired Effect is selected. DIGITAL NOISE The uDSP effects card generates some high fre- quency noise (50kHz), which is a normal product of DSP processing. This does not affect amplifier

24、performance, but may be visible when observing the output of the amplifier on an oscilloscope. . BULLET 15 DSP (This is the model name for warranty claims) * * Non-serviceable part.
