I bought a used Pod Pro that was missing the transformer. I bought a cheap 9VAC 1500ma plug-in power adapter cut the end off and soldered the wires to the PC board. Works perfectly. Now that I know the unit is OK, I contacted Line 6 support, and the proper transformer is still available, so I intend to go that route. FYI, the plug-in power adapter for the original Pod is 9VAC 2000ma. I expect that is closer to the rating of the proper transformer.
