Kit: MX659N18; Minnow4 speaker
Not really designed with DCC Sound in mind, the Bachmann/EFE Class 17 Clayton can have sound fitted though, without too much
Remove the cab and fuel tank and of course the Next18 blanking plate. Cab seats etc. just drop out (gently push cab lugs from
underneath the running plate as this is a little flimsy).
Gently lever off the Next18 circuit board. Be careful as it is attached to the motor by hot glue “gunge” or something similar,
This also covers some of the wires and must be carefully removed in small sections so as not to pull any wires off the circuit
When all the glue is removed SP+ and SP- connections will be found on the circuit.
Attach speaker wires to circuit board (black wires used instead of the usual purple as they do not show up through cab
There is room to feed the speaker wires up the side of the motor, drill two small holes in the cab interior. Reattach the
circuit board to the underside with BlackTack or similar. Test that the loco runs correctly before further progress.
Despite the small size of the MX659N18 sound decoder, a little modification is required to the fuel tank molding, to allow the
end of the decoder to poke through.
Replace the cab interior, feed wires through and solder to the Minnow4 speaker. Test sounds., then attach the speaker to top of
cab interior with glue or BlackTack. Replace cab on loco.
