CIRCUIT DESCRIPTION
PREAMP
J1 is a high sensitivity input which can be driven with as much as 2.5 volts RMS. J2 is a low sensitivity
input which is recommended for Bass Guitars with active pickups, and can handle as much as 5 volts
RMS.
U1A is a “cheater” Sallen Key filter with gain. R79 and C82 create a gradual boost in the high frequencies.
This sets up the initial response of the amplifier. C43 and C44 are used for local power supply decoupling
for the first two op-amp stages. This minimizes noise and hum in the front end of the preamp.
U1B is a variable gain stage. The Gain Control is used as the feedback resistor. This allows a gain
adjustment from less than 1 to about 10.
At the input of U2A, the DEEP enhancement switch boosts and extends the low-frequency response.
Within the negative feedback loop, the BRIGHT enhancement switch adds high frequency “sparkle”. The
output of U2A drives the Notch Filter circuit. When engaged, this filter provides a narrow band notch of
about –20db at 650 Hz. The signal then feeds a unity gain amp (U2B) and couples to the first tone control
stage.
From the active tone controls the signal is routed to the second Gain stage (U8B). If the DeltaComp is off,
switch S5B places Q1 & Q2 into the feedback loop, where they are biased asymetrically to provide non-
symetrical soft clipping, which simulates a tube sound. The diode junctions Q1,Q2, CR1 and CR2 drop a
constant knee-voltage independent of current. As the signal increases above a certain level, the constant
voltage alters the feedback current to the op-amp in a non-linear fashion. This non-linear transfer
characteristic is what rounds off the resulting signal into a tube-type, soft-clipping waveshape. With the
DeltaComp engaged, the soft-clipping circuit is disabled.
CHORUS
The input signal to the Chorus circuit is capacitivly (C61) coupled to U10A, which drives the Bucket Brigade
Device (BBD) U13. Trimpot R105 sets the DC bias for U10A and U12A. When properly adjusted, the
output from U10A & U12A will display symmetrical clipping. (Refer to the adjustment procedure on the
service diagram). The BBD is clocked by U14 at 180kHz. The 180kHz carrier clock is Frequency
Modulated by the Low Frequency Oscillator U11, which deviates the carrier at maximum DEPTH from
60kHz to 300kHz. The RATE of deviation runs from about 0.3Hz to 8.7Hz. The FM deviation on top of the
BBD delay results in a pleasing choral effect.
C62 and R107 (@U10A) provide pre-emphasis above 7kHz. At the output of U12A, R121 and C74 provide
the de-emphasis. This helps to reduce noise. C64, C65 and C67 filter out clock noise. The Dry and
Chorus signals are summed at U12B and then fed to the power amplifier. Via the Chorus select switch or
the footswitch, the Chorus effect can be switched on or off. The collector of Q4 provides the control
voltage which enables U11, and determines the state of JFET Q5. A –15Vdc from Q4 enables U11 to
oscillate, and pinches off JFET Q5, which removes the ground from the node between R123 & R124.
DELTACOMP
The signal from the preamp feeds from P1B pin 4, through a ribbon cable, to P1A on the power amplifier
PCB. The signal couples (via C1) to the unity gain amplifier U1B. U1B contains a closed loop (gain of 1)
negative feedback path, along with positive feedback through the inverting Operational Transconductance
Amplifier (OTA) U2. U1B and U2 make up the gain reduction circuit for the DeltaComp clip protection
feature.

BXR 200
DELTACOMP(Cont)
The attack and release circuit for the DeltaComp is made up by the Diode, Resistor, and Capacitor network
which drives the Base of Q19. Comparator U1A senses the voltage from the Collectors of Q20 & Q21.
When the power amplifier approaches clipping on a positive swing, the collector of Q5 pulls up R56, which
turns on Q20, transferring –16Vdc to the collector, pulling down R60. This causes the output (pin 1) of U1A
to switch from +15Vdc to –15Vdc, lighting the DeltaComp/Clip Led. Note: when the DeltaComp is disabled,
the Led indicates clipping of the output stage. WIth the DeltaComp enabled, the Led indicates an active
DeltaComp circuit. The negative control voltage from R60 also feeds through P1A to P1B on the preamp
PCB. The voltage is routed to the DeltaComp switch (S5A), located on the front panel. With the switch
engaged, the control voltage is sent back through the ribbon cable (via P1 pin 6) to the attack/release
circuit.
The negative voltage drives through Diodes CR31-CR34, and charges Capacitors C16-C19 all at once in
parallel as a one pole filter through a single time constant of R60 X (C6+17+18+19) or 2.2k X 8.8 uF = 19.4
mSec. As they charge, Q19 turns on and provides current to pin 5 of the OTA (U2). The current controls the
output amplitude of U2. The inverted signal from U2 mixes with the input to U1B providing cancellation
which reduces amplitude of U2. The inverted signal from U2 mixes with the input ot U1B providing
cancellation which reduces the input to the power amplifier. This prevents the amplifier from clipping.
When the output of the power amplifier is reduced, the output of U1A toggles back to +15vdc. Due to the
blocking action of Diodes CR31-CR34, Capacitors C16-C19 are forced to discharge as a 4-pole filter with
different time constants through R55. R51 prevents Parasitic oscillation while Zener CR30 provides 2
slopes which results in smoother limiting.
When the power amplifier approaches clipping on a negative swing, R62 is pulled low, turning on Q22 which
pulls up the Base of Q21, transferring –16vdc to the collector.
POWER AMPLIFIER
JFET Q1 and associated components provide a 4-5 second turn-on delay for the audio input to the power
amplifier. When the power is switched on, Capacitor C5 charges through Resistor R7. The negative Gate
voltage pinches off the JFET, removing the ground from the input of the amplifier. When the power is
switched off, C5 immediately discharges through Diode CR1, grounding the input of the amplifier.
TROUBLESHOOTING TIP: Check for proper operation of this circuit when experiencing excessive turn-on
or turn-off “Pops”, or no output when signal applied to the input. Many times the JFET itself can be the
culprit. NOTE: Excessive turn-off “Pops” can also be caused by uneven discharge of the +/- power
supplies. Usually a mismatch in the Filter Capacitors will cause this problem. Its easy to look at both
supplies on an oscilloscope. Invert one scope input and check for even discharge to zero volts.
Q4 is the current source for the Differential Amplifier (Q2,Q3). For the Diff amp to work properly, one half of
the current from the current source must flow through each leg of the Diff amp. If the same amount of
current flows through each leg of the Diff amp, the voltage drop across resistors R14 &R15 must be the
same. If not, there will be a DC offset at the output of the amplifier. The overall gain of the amplifier is set
up around the Diff amp. R16 (27k) is the feedback resistor and R17 (1k) is the pull-down resistor. Rfb
+Rpd ÷Rpd = Av. Therfore 27k + 1k ÷1k = 28k ÷1k = 28Av.
Q9 & Q10 make up a voltage amplification stage. Again, to operate properly, the same amount of current
must flow trhough these transistors. Thus the voltage drop across R20 & R21 must be the same. Diodes
CR16-CR9 (BYV26D) make up the Fixed Bias circuit for the output transistors. The bodies of the Diodes
are mounted through the heatsink to properly track the temperature of the transistors. These Diodes were
selected because they exhibit a 2mV decrease in Knee Voltage for every 1 degree (Celsius) increase in
temperature. The Collectors of Q9 & Q10 are at 0 volts. Therefore the Bias Diodes provide 2 voltage drops
(1.2 volts) to the Base of Driver Transistors Q13 & Q14. One Diode drop (0.6 volts) Biases on the Driver
Transistors. The remaining 0.6 volts drops across the output transistors (Q15-Q18) in parallel, Biasing them
on.

BXR 200
Transistors Q11, Q12, and associated components comprise the Current Limiting or Short Proof protection
circuit. There are usually two conditions which demand excessive output current from the amplifier. A
shorted speaker cable, or a load impedance which is below the minimum rating of the amplifier. If these
conditions occur, the voltage drops across the Emitter Resistors (.33Ω5 Watt) will dramatically increase.
On the positive side of the amplifier, C11 charges through R29 & R34. On the negative side C12 charges
through R30 & R35. Htis will cause Q11 & Q12 to turn on. This limits the amount of signal which is
available to the Base of the Driver Transistors (Q13 & Q14). CR20-CR23 make up a latching circuit that
senses the signal through R22. This ensures that Q11 & Q12 turn on hard in conduction. When the fault
condition is removed from the output, the current limiting circuit will remain latched up until the input signal is
removed.
Q13 & Q14 are the Driver Transistors for the output section. Q15-Q18 are the output transistors. Notice on
the schematic that the Base resistors carry the “Fp” designation. Htis indicates a Flame Proof/Fuse Type
resistor. They won’t burn and they act like a fuse when exposed to an over-current condition. This prevents
catastrophic damage to the output section. If an output transistor shorts Base to Collector or Base to
Emitter, the resistor will simply open. IN many cases the amplifier will continue to operate, but at a reduced
power level. An increase in distortion may also become apparent. When replacing these resistors,
ALWAYS use the Fuse Type OEM part.
