Items used:
ESU 58816 LokSound 5 Micro with NEM651 (6 pin) plug
DCCSound Premium speaker for the Auscision 73 class
Note: This installation pertains to the 2nd release of the 73 class, with updated electronics.
The model is disassembled by first removing the two couplers including mounting screws.
Set these aside in a safe place.
Next, gently shimmy the body up and off from the chassis.
Most of the installation time involves putting the speaker into the cab.
To access the cab space, the cab structure must be removed from the walkway and long hood assembly.
The cab is glued to the walkway and must be unfixed at the locations shown with the red arrows. The bond can be carefully unfixed using a small tool.
It helps to unfix the short hood from the walkway also, as the green arrows show.
The walkway handrails must be temporarily disconnected from the cab too.
The cab and short hood is then lifted up and off from rest of the body assembly.
The 6 pin DC dummy plug is removed from the long hood end and the decoder's 6 pin plug connected. The decoder's plug is aligned such that the * faces downwards in the model.
The decoder is then positioned and held with Kapton tape.
Next, the speaker wires are fed out of the long hood at the cab interior, and soldered to the speaker. The speaker is then fixed with double sided mounting tape or glue, such as MicroScale KristalKlear.
Next, the body assembly is placed back down over the chassis and couplers refitted.
3 micro switches, accessible via a hatch in the long hood enable independent switching of headlights, numberboards and marker lights.
