For Athearn Genesis Slab-Side Gas Turbine locomotives, the UFIT-30D9-RC1 and UFIT-30D5-RC1 Rectify systems drop right in. This set includes one 9mmH 30D9 for the front position and one 15mmH 30D5 system for the rear location. PCB-style decoders such as Loksound Direct and Tsunami2 PNP are not impacted at all.
 
The speakers come fully assembled and tested.
