Congratulations, Roland. I think I am able to share in the sense of satisfaction that this sort of re-animation brings. I had an old MARX M10000 set sitting on a display shelf for more than 30 years. The motor was busted up, beyond repair, when I bought it at one of Ted Maurer's auctions (I know that these motors have a reputation for being bullet-proof, but this one was beyond recovering). A year or so ago I finally found a replacement motor for sale at a reasonable price and it was wonderful (!) to behold that old train running around the track for the first time (for me, anyway).
Good job getting your PAs up and running. And, a bonus to have some spare A units with which to experiment.
Sam
