I just bought an Athearn F45 with a Tsunami sound decoder. When It hits a dirty spot in the track, the sound resets. I need to add a capacitor, but don't know what size or where to hook it up. I asked on the Soundtraxx Group, but have a feeling they are mostly HO guys. I don't know which model Tsunami was supplied with the Athearn loco. I know we have some decoder and sound experts on the list. Hopefully one can chime in. Thanks, Pete
