Thanks all. I already knew about using Bachmann's DC controller but was hoping for a more economical method. I'm suspicious about the connectors (3 wire instead of two) that Bachmann is using for the interconnects since only two wires should be needed. My guess is that in the connection between the DC & DCC Controller it is set up such that one is a common, another supplies the adjustable output from the DC Controller and the last is the 16 VAC, BUT without the internal wiring of the controllers, this is only a guess and I would not want to experiment because it could blow the DCC controller. If I'm right though, removing the DC Controller but doing a special wiring into the DC Controller input to the DCC Controller, whereby a short between the Common and the output for the DC Controller would fool the DCC controller that the DC Controller is connected and set to zero volts out.
