IMPROVED DESIGN!
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 or between the back of the enclosure and the weight. There are arms that hold the speaker in place, preventing the driver from touching the weight and providing a path for the truck wires to pass through.
In the GP7/9/18, a Decoder Buddy MINI 21-pin motherboard can be installed in place of the stock PCB, but you will need to trim the excess pin-height once the decoder is installed. If you file the small nubs on the weight, you can install a BOWS-RS3S speaker along side the Decoder Buddy MINI and have a dual-speaker installation.
The Nix Trainz N18 NEXT18 motherboard easily fits (photos of this install coming soon).
In the SD7/9, if you 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 (now LLPR-7918) 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.
