The Graham Farish N Gauge LMS Ivatt 2MT Class.. installation guide for DCC sound using Zimo MX648 and modified SugarCube7 speaker...
Tender top off, remove factory circuit board and 6pin DCC socket. File down screw mounts where circuit board was fixed.
The kit that's going in... a Zimo MX648 sound decoder and YouChoos SugarCube7 speaker, with the top totally filed off.
There is very little room at the back of this tender, so it has to use the body as the speaker enclosure top.
File down and test-fit until it all goes flush. A MicroCube is an alternative, but won't be as loud as the SugarCube.
The MX648 hard-wired to pickups and motor. Protective sleeve removed to gain even more height, although probably
not strictly necessary - the speaker end is the really tight bit. A little Black-Tak to improve the speaker seal and hold
everything in place.
The finished article. It is a light-weight engine, so will benefit from regular cleaning, but sounds great with its
high pitched whistles.
