Hornby SR Schools Class with Zimo Sound

Kit: MX645R; SugarCube24X15X08-2W; SuperCap17000uF

The ever-handsome Schools Class, this excellent Hornby model has been renamed from "Wellington" to "Epson" by TMC, and here we'll add DCC Sound and Stay-Alive into the tender.

Top off the tender reveals the 8pin DCC socket. We remove the supression component which is not necessary under DCC and can cause motor control problems if left in.

Since we want to add the SuperCap for stay-alive, we need to remove the 8pin socket, hard-wire the decoder, and place the SuperCap where the socket started out.

With the SuperCap loosely in place, we measure up for speaker size, trying the tender top to make sure it goes in vertically. A dual SugarCube 24X15X08-2W is the best fit for the space.

The decoder has its' function wires trimmed, as we're not adding any lighting, and we simply connect the red+black wires to the pickups, orange+grey to the motor wires, purples to the speaker, and finally the grey+blue from the other end directly to the SuperCap.

Metal weight back in, all secured down, and all fits a treat, without having to cut any plastic either!
