Dimmer unit mod

Hello, here are a few pics about how I modified original Dimmer Modules that came with 757 nose section to use the crytical velocity dimmer units I bought to dim all cockpit backlighting. Enjoy!

Here is how the unit presents after case removal

Removing screws that keep the electronic boards in place

Electronic boards removal and wire cutted out

Those round supports are gonna be helpful....

Removing the AC transformer

Case is clean from old stuff, ready to accomodate new DIM board!

Important to keep same pinout for easy cabling later on with MIL connectors

Critical Velocity board

Round supports reused to keep the board in correct position

Rewiring complete following original pinout

Board fitted with supports

New DIM unit is ready to work!

PNP ready!! :)
