Heljan O gauge Class 47

Heljan Class 47 with MS950 sound

Kit: MS950; LOK950PL adapter board; YLR603010 + YLR302815 speakers

The 2022 edition of Heljan's Class 47 is our starting point here. This has smaller motors and flywheels than the older model, so a little more space to work with.

The factory PCB is removed, and wires transferred across to the Zimo LOK950PL adpater board. We reused part of the feet from the original mount so that the LOK950PL is raised a little off the platform - just makes it a little neater.

We build a simple support for our YLR603010 speaker at one end, straddling the bogie pivot.

At the other end, our YLR302815 speaker is fixed to the cab back wall, just enough space for the bogie to clear as it pivots.

Wiring is attached to the adapter board, separating the front and rear lights so we can have directional control of everything.
