Dempsey Posted August 14 Share Posted August 14 There is just something about American tractive power. After recently picking up my first American locomotive, an Athearn SD40. I decided to update and increase the detailing of the locomotive. Starting with adding sound. Firstly removing the old eight pin motherboard and replacing it with a new 21pin motherboard with speaker and sound decoder from DCC concepts. 20240814_183234.mp4 5 Quote Link to comment Share on other sites More sharing options...

clehap Posted August 17 Share Posted August 17 DJ Thanks for getting back to me. Looks and sounds like you've done a great job on that model! My reluctance to do it myself is just in being intimidated by the amount of wiring on the Class 071 model. I may well give it a shot.
