Hornby OO SECR Wainwright H with MS sound and stay-alive

Kit: MS481; SugarCube6; STACO1

Another look at a Hornby H Class to find a neater approach with more up-to-date kit...

We have to take out the socket and temporarily remove the motor in order to access the wiring, and the terminals for the motor. It will be a tight fit, so make as much space as possible with minimal wiring.

The screw mounts for the DCC socket are ground down to flatten that area - this will be useful for the decoder to sit more comfortably.

We carefully remove the body from the frame and file back toward the cab so that a speaker fits on one side and the GoldCaps from our STACO1 kit fit on this other side. The GoldCaps will have to be very neatly soldered to go in the side tank.

With unnecessary wires removed from the decoder altogether, wire length shorted to fit the space, and components protected with Kapton tape, this all carefully goes into the various positions.

It is a tight fit, but a neat one, and the results are quite stunning. The STACO1 stay-alive provides huge backup time once charged up, and the SugarCube6 speaker is loud enough with the MS481 to produce excellent results.
