We recently installed a Loksound Select Micro in an older Walthers SW1. These Walthers units were produced in the late 90's and early 2000's by Roco and featured a smooth running mechanism and a well-executed plastic shell. For this project, we disassembled an ESU PowerPack stay alive and separated the control board from the capacitor. The Loksound 73800 Slect Micro decoder was placed over the motor with the PowerPack control board stacked over the decoder. TTX 3mm Warm White LEDs were used along with a TDS SuperSonic Mini speaker & enclosure.
