This is a Rectify Series drop-in speaker system for Life-Like Proto 2000 GP7/9/18 and SD7/9 locomotives. The system sits on the chassis over the short-hood drive-shaft and fits between the cab seats in the cab. This is a fast, simple way to add sound to these locomotives without modifying the frame. Use two small strips of mounting-tape to secure the feet to the frame. The truck-tab may need to be trimmed or bent down a bit.
The GP7/9 has room for a hard-wired decoder install once the stock PCB is removed. A LokSound Direct, Soundtraxx PNP or a 21-pin motherboard configuration will likely require some weight milling/cutting/filing.
In the SD7/9, if you use a rotary tool and nip off the two screw-mount posts from the stock PCB, you'll have a good 10mm of clearance under the long-hood. Depending on the style of your decoder install, a 9mm high UFIT will mount in the rear. Pictured is a 15mmW x 40mmL UFIT-5940-RC1 (now UFIT-0940) speaker mounted behind a Nix Trainz Decoder Buddy along with the cab-mounted LLPR-79FR speaker.
The stock lightpipes will need to be trimmed short with a 1206 (or similar) LED glued to them. In some cases the short-hood truck pickup tab may need to be bent down or trimmed shorter.
The speakers come fully assembled and tested.
Dimensions: 15mmH x 13mmW x 19mmL
