Reply to "Early MTH PS1 Loco Won't Come Out Of Reset with Z1000"

A 2080LP was made in 1995. it requires pure sine wave AC, as Lee and GGG posted.

I had a similar situation with a MTH 1994 Premier model of Southern Ps-4 1401 in the Smithsonian that I purchased from a Forumite. It ran only with postwar transformers, as I had suspected it would. I got a board for a 1997 RailKing Ps-4 from MTH Parts, and Wayne Renga of J and W Electronics installed it. I gained Passenger Station Announcements (PSA), and now it runs with newer transformers.

Early ProtoSounds systems (a MTH adaptation of QSIndustries boards) are designed for Lionel Electrical Operating Standards (L.E.O.S.). They have low tolerances for newer transformers with "chopped" sine wave AC. Later PS-1 systems are a bit more tolerant, but "chopped" AC can damage or destroy them, especially when voltage is increased to pull trains.
