Kit: Zimo MX645R with Zimo Dumbo LS26X20X08-1W
DCC sound installation pretty easy in this Bachmann SECR Wainwright 'C' tender - wired MX645 with small Dumbo (LS26X20X08-1W)
and a decent 1000uF electrolytic capacitor for stay-alive. The model actually comes with a 21pin DCC socket, which makes it a very
easy install using an MX644D and smaller speaker, but we want more volume and a decent stay-alive, so have opted to remove the socket
and hard-wire the kit.
Not shown in detail here, but below is an example of a pair of pretty SECR green lined 'C's which have had a full-monty installation, with second
decoder in the loco controlling smoke (with metal chimney) and lighting. Not for the faint-hearted, but shows what can be achieved!
