Bachmann OO Class 08 Diesel Zimo DCC Sound

Example 1: Simple sound

Kit: MX648; SugarCube8

Installing DCC sound in a Bachmann OO Class 08 diesel using a Zimo MX648 decoder. No stay-alive in this one, but a fairly simple installation...

Disassembled, 8pin socket removed, MX648 hard-wired to pickups and motor...

Example 1

Hole to thread speaker wires through...

Example 1

Tidy the wiring and pop the main part of the body back on, SugarCube and crew in place...

Example 1 Example 1

Wait for the glue to dry, and finally put the cab back on...

Example 1 Example 1

Example 2: Bigger speaker and big stay-alive included

Kit: MX648; IceCube18X13X07-1W; LifeLink + 17000uF SuperCap

A more ambitious approach, but well worthwhile, and frankly not a whole lot harder. The big SuperCap really helps with running reliability in this stiff little model, and the larger speaker gives it more presence too.

Example 2 Example 2

SuperCap is protected in Kapton tape and mounted at the front - care must be taken not to allow the end of the motor shaft to foul on the capacitor though.

Example 2

The sound decoder goes vertically in front of that...

Example 2

LifeLink PCB goes in front of that, and we root wires for the speaker back toward the cab - a small hole has these wires threaded through, which we can trim to length and solder to the speaker once the main part of the body is back in place.
