CHASSIS REMOVAL is accomplished by first removing two (2) screws from each cabinet side panel and two (2) screws from the top of the cabinet. Disconnec
12、t the ” speaker plug(s) from the speaker jack(s) and then slide the chassis toward the rear of the cabinet. 2. BLUES DELUXE REISSUE MAIN PCB RE- MOVAL is accomplished by removing the following items: All Vacuum tubes, all knobs in- cluding washers and nuts (8), four (4) jacks, nuts and washers. Disc
13、onnect the transformer and primary leads at P1-P12, P15-18. Remove (1) chassis ground screw, six (6) screws at the standoffs attached from the bottom of the chas- sis. 3. BLUES DELUXE REISSUE BREAKAWAY PCB REMOVAL is accomplished by discon- necting wires from P13-14 and P19-20 then removing thirteen
14、 (13) screws which attach the vacuum tube PCB to the chassis from the bot- tom. Also unsolder gray wire from the external speaker jack and green wires at pilot lamp. PCB EXCHANGE POLICY Parts marked with a single asterisk (*) in the Part Lists are not field replaceable. If a failure due to one of th
15、ese components is detected, please contact the FMIC Customer Service Department to order the complete PCB Assembly. Blues Deluxe Reissue (This is the model name for warranty claims) 5 CIRCUIT DESCRIPTION PRE-AMPLIFIER The guitar signal is input to J1 for high gain and J2 for lower gain. When both in
16、puts are used, both signals receive low gain. V1-A and V1-B provide two gain stages while R6 provides clean volume control. The tone stack, composed of R13,14,15 and associated components provide treble, bass and middle tone control respectively. V2-A provides gain lost in the tone stack. When the c
17、hannel select switch is depressed, relays K1 and K2 are energized. This has the effect of disconnecting the volume control, thereby increasing the gain of the first stage while removing the short across R7, drive control, allowing it to control the amount that V2-A is overdriven. R26 is now in the c
18、ircuit and is used to control the volume of the overdriven signal. The clean or distorted signals are input to opamp U1-A, employed as a unity gain buffer to develop the PREAMP out signal at J3. Opamps U2-A and U2-B function as reverb tank drive and recovery respectively. When an external signal is
19、plugged into J4, POWER AMP IN, the internal pre-amp signal is diverted from the power amp and the external signal instead is fed to the reverb drive and the power amp. POWER AMPLIFIER R40 and R38 sum the signals from the preamp and the reverb tank and feed them into the power amplifier. V3-A and V3-
20、B serve as phase splitters which produce two out of phase signals for the purpose of driving V4 and V5 which act as a push- pull pair in a class A-B power amplifier. T1 matches the 6L6 plate impedance to the speaker load. POWER SUPPLY The line voltage is fed to T2s primary through the line fuse, F1,
21、 and the inrush current limiter, RT1. The input voltage is then stepped up or down as needed, rectified and filtered to produce the high X, Y, Z and B+ voltage for the tubes as well as the +/- 16V rails for the opamps. A 6.3VAC secondary powers the power indicator lamp and the tubes heaters. FOOTSWI
22、TCH INTERFACE A two button footswitch (P/N 0994056000) is included for remote switching of the channels and reverb. When the VAC signal is clamped by either the internal (S2) or external (footswitch) diodes, a positive or a negative level that is being compared to a reference by comparators U3-A/B i
23、s changed, causing the comparator outputs to change state. U3-b senses the positive level change and energizes K1 and K2. U3-A senses the negative level change and turns on Q2 which mutes the reverb. U4-A and associated circuitry act as a zero crossing detector which mutes the preamp during channel
