Since the ZDC-24 power supply isn't available yet and the Radio Shack 18-24 power supply can't be located with an "M" barrel on E-Bay, as all sellers indicate No Tips, what is a approved source of power that plugs into the TIU AUX port. I've read the forum's discussions and there are several recommendations, however; one example was an RS-24. Searching E-Bay found an RS-24, but the manufacturer on the forum wasn't specified.
I'm helping set up a 16' X 32' layout with nearly 1,000' of track and I need a little assistance on what to power the TIU with until the new MTH device is available. I read that the MTH HO scale power supply was an approved alternative. Is that a good work around until the ZDC-24 becomes available?
By the way there are multiple listings in E-Bay for the old Radio Shack power supply but no tips.
