Hornby's BR Standard Class 8 model 'Duke of Gloucester' makes a relatively simple conversion to DCC sound. The model comes with
a large fly-wheel on the motor, which helps with the fact that there are no pick-ups on the tender. However, we will install the amazing
SuperCap68 which is a 6800uF/15V super capacitor instead, so there is no benefit in keeping the fly-wheel, and the additional space
will prove very useful.
Therefore our first step is to remove the motor and grind off the fly-wheel...

In fact, our model will also be fitted with full lighting and a smoke generator, so in order to create as much space as possible, we remove
the 8pin DCC socket. The SuperCap68 will be seated where the DCC socket was. A SugarLump speaker is placed where the fly-wheel was. A Zimo
MX645 sound decoder is mounted above the capacitor, still leaving enough space for the bulk of wiring from our various lights.
Note the trenches routed out for the lamp wires to sit inside, so they are neat and flush.
