O Gauge Heljan Class 17 Clayton with Zimo MS sound using booster board

Kit: MS450PluX22; ADAPLU booster; YLR603010 speaker; SuperCap17000uF

Similar approach to the MX Booster install guide, but this time using an MS series Zimo sound decoder in a PluX22 Booster board.

Speaker compartment underneath is an awkward shape for anything but a round speaker, which we're tried a few of, and found they don't perform well enough to be worthwhile.

The model provides an 'L' DCC socket, which will take an MS950 sound decoder, but we didn't have any at the time of this installation, so go with a PluX22 booster approach instead.

We will retain the fan PCB, though moved a little to create space for our YLR603010 speaker.

We begin the process of transferring the model's wires to appropriate solder pads on the ADAPLU booster board (solder pads).

All wired in now, we test everything out using the MS450PluX22 sound decoder plugged in.

Lighting wires are connected as follows F0Fwd for front headcode, F0Rev for rear headcode, FA1 for front reds, FA2 for rear reds, FA3 for fan.

A SuperCap17000uF is used for the stay-alive, which is BlackTacked to the side after wrapping in Kapton.

The YLR60301 has its' lugs cut off and it then just fits between the cab and the fan in the roof, attachced up with BlackTack.
