Example 1: Zimo MX648, modified SugarCube, grinding, total rewire

This is a photo guide showing the Zimo MX648 and SugarCube speaker installed in a Farish N gauge Class 55 DP1 Deltic Prototype diesel.

Chassis modifications to accomodate speaker and decoder:

Decoder installed, connected to motor terminals and pickups soldered to cut-out rings from the original factory circuit board, screwed down (nice bit of reuse!):

CT SugarCube with reduced and shaped enclosure now in place - still plenty of volume from this great speaker:

Reuse of the resistor bank from the original factory circuit board, in preparation for lighting to be rewired:

Cab interiors back in place, drivers added, and SMD white LEDs installed for cab lighting:

Original lighting boards back in, wired up, via resistor bank:

Added kitchen foil to allow up-facing cab lights to difuse light around the cabs (must make sure the foil doesn't short on the LEDs though!):

Add taped down and nice and neat:

Example 2: Zimo MX649, SugarCube7, less grinding, keep factory circuit board

Here is another example, with a simpler installation, retaining the original factory circuit board, and placing a smaller speaker in the fuel tank (less grinding)...
