The Dapol N Gauge 9F - installation guide for DCC sound using Zimo MX648 and Zimo 9mm SugarCube speaker...
Here's the donor model...
Tender top pops off to reveal the usual Dapol angled DCC socket board, which we must remove completely
including the mounts, as this is where the SugarCube speaker will go. A YouChoos 7mm SugarCube will give
good results, but we decide to push the install a little further and used a standard Zimo 9mm SugarCube.
Double-sided sticky pad to secure the speaker. Remove unwanted wires from the decoder, shorten the wires
approximately, and use a thin double-sided tape to loosely stick the decoder on top of the motor (don't use
the tape over the motor opening itself though!)
Carefully solder up the 6 wires (purple to speaker, red & black to pickups, orange & grey to motor) and
test direction of travel - if backwards compared to what was expected, just swap the orange and grey
Tuck as much of the wiring down the sides of the speaker rather than on top, as it will be tight, and ease
the tender body back on until it clips securely.
The decoder sits too high on the motor to use the original coal moulding, so we use a strip of electrical
tape, then work some Black-Tak into the gaps, shaping around the edges, then a little Gel SuperGlue
covered in crushed Woodland Scenics coal ballast - nice effect!
