Hi folks.
New year; time for another sound install, this time in my Atlas GP 30. Since this installation used the same basic techniques as my RS11 and GP7 (both of which are in threads on here somewhere), I won't do a detailed how to, but I do have photos showing the component layout below. One thing that is a bit different: the NKP used a horizontal front headlight on the low hood. The Atlas model doesn't have this, so I used a Detail Associates detail part to make this. I drilled through the shell and used some Micro Krystal Clear from Microscale for the lenses. As you will see, the headlight is lit with a sunny white surface mount LED mounted on the front of the chassis.
I took a bit more video this time to illustrate not only the sound, but also the terrific motor control you get with ESU's LokSound decoder. Link to YouTube video is here:

The speaker is the Knowles Fox (which was still available at Digikey for immediate shipment today) in an enclosure made of .020 styrene, 6mm high overall. The installation is pretty easy - the only frame milling I did was at the front, cutting off about a half-inch of the channel for the PC board to fit the front of the Loksound there.
I used surface mount sunny white LED's from Richmond Controls for the front and back lights. Here's a shot of the nose of the chassis showing the front LED:
The rear LED is mounted on the speaker enclosure:
And here are some photos of the completed installation:
Tecnnically, the GP30 was the first of the 567 prime movers with a turbo, but I just love the sound of the Roots blown 567C, so that's what I used for this one.
