Hornby OO J15 with Zimo MS Sound

Kit: MS480; IceCube25X18X07; STACO1

Revisiting a J15 with Zimo's MS480 decoder this time...

The biggest speaker we can get in is the IceCube25X18X07, but even this requires removal of plastic under the coal load - easy enough though...

A quick test-fit to see exactly where the speaker will need to be positioned.

We remove the 8pin DCC socket from the model and hard-wire our MS480, removing all of the unnecessary wires (lighting) to make the installation as compact as possible.

The decoder is covered in Kapton tape and tucks through the aperture in the metal weight, with IceCube speaker fixed on top.

We retained the stay-alive wires from the decoder in order to add the STACO1 stay-alive kit. This is a PCB plus 3 mini GoldCaps, joined in series.

The STACO PCB is wraped in Kapton and placed down in the well, and the GoldCaps are then also protected with Kapton tape, and BlackTack'd into position - far enough back to avoid the tender body clip being fouled by them.

A little BlackTack to hold the coal load on, and stop it vibrating, then we finish with some lump coal which is fixed in with UHU glue.
