Kit:: MX648R (plugged in); SugarCube7 speaker
Going for a really simple approach on this one...
Just complicated a little because we want a firebox glow LED (nano)...
The MX648R plugs straight into the model's 8pin DCC socket, and a SugarCube7 is perched just ahead on some Black Tack.
Body on, custom weathering applied and off we go!
Kit: Zimo MX648 hard-wired and SugarCube7 speaker, SPEIKOMP kit and 3x 330uF Tantalum stay-alive
Donor model, already weathered by TMC...
The 8 pin DCC socket has sprung-loaded pins that go down to the pickups, so best to keep this. However, we need lots of space,
so we chop all but the pins and the screw retainer. The MX648 decoder has the pickup wires soldered direct to the top of the
pins. The decoder has has all unwanted wires removed, and the sleeve replaced with Kapton tape to make as thin and compact as
You don't necessarily need to do this, but for good running we have added a SPEIKOMP kit and 3 x 330uF Tantalum capacitors as
stay-alive. Capacitors joined in parallel and all bits protected with Kapton tape.
All connected with relatively short wires, and secured with some double-sided tape, or a little Black Tack, mounted diagonally
to fit better. SugarCube7 fits in the side tank.
Done, and back together...
Kit: MX648R (or MS480R); SugarCube7; Lais stay-alive
This time we decide to remove the metal weight in one of the side tanks so that the kit can all fit in without having to
This mostly works fine, except that the suppression components in the model cause problems for the motor control from the
decoder, so we must remove them. In this J50, the offending component is a surface mount capacitor underneath the 8pin PCB
marked as 'C1'. Desolder (or snip) this out and everything behaves perfectly!
