Installation Instructions
I KW AUDIO AMPLIFIER UPGRADE
KIT NO. 26677701
These instructions will assist in the installation of the 1 KW audio amplifier, part no. 61170003, in Rowe jukeboxes with
1000 watt audio systems.
Purpose:
To install the 1 KW Audio Amplifier along with the output resistor board.
NOTE: The output resistor board included in this kit must be installed on the Audio Output Transformer
Assembly. This is to prevent damage to the 1KW Audio Amplifier.
Tools Required:
1/4” Nut Driver, Pliers, Philips Screwdriver

Step By Step Instructions:
1. Turn off power inside the jukebox and unplug the jukebox power cord from the wall outlet.
2. Using the 1/4” nut driver, loosen the four (4) screws holding the audio output transformer assembly and
remove this assembly along with the 4 wire transformer output harness and the 3 wire transformer to crossover
board harness which are attached to the audio output transformer assembly. On some jukebox models the
3 wire transformer to crossover board harness cannot be easily removed from the jukebox cabinet. In this case
note the locations of the pink, violet and black wires from the terminal strips on the front of the transformer
assembly. The transformer assembly can now be removed from the jukebox.

3. If the transformers on the audio output assembly are not mounted in the positions shown in Figure 1 which is
with the transformer wires exiting the transformer toward the terminal strips then the transformers will need to
be rotated 180° on the transformer chassis so that they are in the correct position. This is necessary to have the
correct length on the yellow transformer wires.
Both transformers must be positioned so
that the transformer wires exit toward the
terminal strips on the chassis.

4. Disconnect the two (2) yellow transformer wires from the binding post strips at the E7 locations of channels 1
and 2 on the audio output transformer assembly. Connect the two (2) yellow jumper wires from this kit onto
the same E7 locations. See Figure 1. If you rotated the transformers in step 3 they can be mounted back on the
transformer chassis. Insert the pink, violet and black wires from the crossover board harness through the
access hole in the resistor board included in this kit. Insert the wires in the direction shown in Figure 2.
Next, insert these three (3) wires through the access hole in the transformer assembly chassis. See Figure 2.
Attach these three (3) wires to the previously used locations on the binding post strips.

5. Attach the yellow transformer wires to the resistor board as shown in Figure 3. The yellow wire from
channel 1 transformer goes to the terminal on the resistor board marked CH1 XFMR (T3). The yellow wire
from channel 2 transformer goes to the terminal marked CH2 XFMR (T4). The two yellow jumper wires attach to the resistor board as follows:
The yellow jumper from E7 on channel 1 goes to the terminal on the resistor board marked CH1 TERM
STRIP (T2), and the yellow jumper wire from E7 on channel 2 goes to the terminal marked CH2 TERM
STRIP (T1).
Refer to Figure 3 and route the transformer harness in the direction that it was before the assembly was
removed from the jukebox. (The transformer harness can be routed in either direction shown in Figure 3. The
routing depends on which jukebox model the amplifier kit is being installed in). Attach the resistor board to
the audio output transformer assembly using the two (2) #8-32 x 1 Hex WRHMS from this kit. See Figure 3.
Install the audio transformer assembly back into the jukebox. Tighten the four (4) mounting screws and plug
the 3 wire transformer-to-crossover board harness back into the jukebox harness or back onto the crossover
board. The audio 4 wire transformer output harness will plug into the new audio amplifier. (Step 6).

6. Unplug all the harnesses in the jukebox that are attached to the audio amplifier that is being replaced. Using
the 1/4” nut driver, loosen the four (4) screws holding the audio amplifier assembly and remove the amplifier
from the jukebox. Place the new amplifier from this kit in the jukebox in the same location as the old amplifier. Plug all the harnesses into the new amplifier, including the audio transformer output harness. It may be
necessary to reroute some of the harnesses to allow them to plug into the new amplifier. Cable ties have been
included with this kit if rerouting is done. Verify that no harnesses come in contact with the CD mechanism in
the CD jukebox.
Also, if this installation is in a CD100I or CD100J with Studio Sound then the audio cable included in this kit
will be used to replace the shorter audio cables from the studio sound board to the new 1KW amplifier audio
inputs.
