I am new to 2-rail DC and am trying to get my first loop running. I bought a used MRC Control Master 20 for this, but that has proved to not work as of yet (I believe the handheld is not communicating with the base). My current 3-rail setup has a Lionel ZW running to a fuze box (see Backshop video), followed by a DCS system and the track. Can I install a bridge rectifier after the DCS system and use the DCS remote to vary the AC input and, in turn, to vary the voltage to the track? What bridge rectifier should I use for this? Someone on another thread recommended using 10 amp ones, will any of the ones on Amazon work?
