Soundchipping an HO Atlas SD35

[Jon Grant 4472]

I finally finished the install tonight after a few busy days at work.

I added some lead to the top of the motor to compensate for what had been cut away. More will be fitted beneath the long hood, when I start on the body.

I modified the 8ohm high-bass speaker to include the LED for the rear light. This was the only way I could get the LED at the correct height. I also had to cut away some of the clear plastic from the lens/numberboard casting so the speaker would fit.

The capacitor wires were shortened to suit and the capacitor sits loosely on a cradle made using the pickup wires and those for the front nose-mounted LED.

Here are the photos










Even without the body-shell in place, I am pretty pleased with the sound quality from the speaker.

Now to start on the detailling and weathering on the loco.
