BASSBREAKER™ 15
(This is the model name for warranty claims)
SERVICE NOTES
As modern day amplifiers are more compact
and sophisticated proper wire dress becomes a
critical issue, both for the sake of Safety and
FCC Certification. It is highly recommended that
before disassembly you take digital photos to
use as a reference during reassembly, for wire
and component dress.
Factory set locations for
wire dress, wire ties, ferrites, and anchors should
be maintained at all times. Use the following proce-
dures to disassemble the Bassbreaker 15 for
service access
. Please note that all coaxial ca-
bles use multi-pin connectors which are all of
the same type. During the removal process for
all of the PCBs these connectors will need to be
disconnected. Since they are all the same in or-
der to prevent confusion and miss-wiring it his
highly recommended that colored markers or
labels be used to ID the proper cable connector
PCB Header relationship. Also again as stated
several photos should be taken to assure prop-
er wire dress during reassembly.
CHASSIS REMOVAL
is accomplished by first re-
moving the five (5) screws from the rear upper
screen panel. Next remove the five (5) screws
which secure the rear lower panel to the cabinet.
On the Combo Version Only disconnect the Speak-
er Terminal Wires at the Speaker. Remove the two
(2) side chassis screws (4 total) on the left and right
side of the cabinet. Now supporting the chassis re-
move the two (2) top chassis screws and remove
the chassis from the cabinet. Access to the inside of
the chassis can then be accomplished by removing
the seven (7) screws which secure the rear chassis
cover and folding it back out of the way.
REAR PANEL PCB ASSEMBLY REMOVAL
is ac-
complished by first marking and unplugging the five
(5) PCB multi-wire connectors at designation #P44-
P48 from the I/O PCB Assembly. Next remove the
two screws holding the Line Out XLR Jack to the
Rear Panel. Remove the two EFX Loop Jack Nuts
and Washers from the rear panel noting their
makeup for reassembly. Remove the six (6) PCB
Mounting standoff screws from the PCB and sepa-
rate the PCB from the Rear Panel.
TOP PANEL INPUT PCB ASSEMBLY REMOVAL
is accomplished by marking and unplugging the
four (4) multi-pin connectors P30-P33 on the Input
PCB Assembly. Remove the Gain Knob, Control
Nut and Washer. Remove the nut and washer from
the input jack. You can now remove the Front Panel
Input PCB Assembly.
SPEAKER JACK PCB ASSEMBLY REMOVAL
begins by disconnecting the four (4) fast-on con-
nectors P107-P110 from the PCB. Remove the
Speaker Jack nuts and washers (Noting their
makeup for reassembly). The PCB can now be re-
moved from the chassis.
IMPEDANCE SELECTOR SWITCH PCB ASSEM-
BLY REMOVAL
is initiated by disconnecting the
seven (7) fast-on connectors noting the color code
indicated on the PCB. Remove the two (2) screws
holding the PCB Assembly to the back panel. The
PCB Assembly can now be removed from the chas-

GAIN/STRUCTURE CONTROL PCB ASSEMBLY
REMOVAL
is started by marking and unplugging
the five (5) multi-pin connectors P39-P43. Remove
the control knob, nut, and washer. The PCB can
now be removed.
