Guys,
I have a few random TMCC technical questions that I hope to get answered. Any help is greatly appreciated!
1) I have an R2LC board with physical damage that took out the yellow/orange component shown in the photo (it normally has two leads). Also pictured is an intact R2LC showing where the part came from. Knowing where it is on the board and seeing the "455" printed on it tells me it's RF related, perhaps a crystal of some sort. Might anyone know exactly what this part is, and if it is available from Digikey or Mouser?
2) Has it ever been documented what purpose the switch serves on the modular AD20 boards that were used from the late 1990's through 2004 or so? There aren't any markings on the board itself that would lend a clue. I've tried the "A" version of the board (for steam loco tenders) and the position of the switch doesn't seem to have an effect on operation. Perhaps it's for the "B" version used in diesels, or for some other purpose?
3) Might anyone have the specs on the Piezo buzzer used for the CAB-1? Or even better yet, might anyone have a buzzer from a dead CAB-1?
Many thanks!
Todd
