I am in the process of DE-decodering most of my locomotives as the price of decoders and the size of my fleet, both aquired and anticipated, make it a budgetary problem I'd rather not deal with right now. My new layout will be DC only, the practical reasons being 1.) The expense of the size unit necessary to handle the size layout I am building and 2.) The number of locomotives I won't be able to run because of the limitations and drawbacks of running "00" channel. Obviously, as old as some members of my locomotive roster are and the sometimes innovative and ingenious ways ( pause to pat myself on the back ) it took to install decoders in them, I don't want to undo them. What I need is a source for this type of shorting chip that fits onto Lenz and Digitrax 9 pin harnesses, either from you folks who may have a couple lying around the workbench or a retailer online who may carry them. I need three or four of them and any help would be greatly appreciated.
