An unusual prototype here, as Heljan have created the 10800 North British diesel in OO. Speaker already fitted (reasonable
SugarCube), lighting, and provision for a 21pin sound decoder, so nice and simple.
Take out the 21pin blanking plate, protect the model's PCB/components with some Kaptop tape, and plug the MS440 decoder in.
The sound decoder has to fit at a bit of an odd angle, as there are components underneath this, quite poorly placed, but not
really an issue as long as we protect them.
