Thank you and Happy Railroading!
This is one of those questions that will get a better response over on the Classic Toy Trains forum. Not that we're exclusive or anything, buy you'll find far more O-gaugers over there.
It takes an iron man to play with a toy iron horse.
Does the ZA transformer use Pulse Modulated Power or is it variable DC?
Edit: My mistake. I read BLI and not MTH. No wonder protosound 2 didn't sound famaliar. I now remember it's part of DCS by Mike Wolfe of MTH. I'm not an O-scaler though.
Mr. B is correct. Classic trains is your best bet.

I ran across a post where a gentleman wanted to run an Mth Protosound 2 Engine using his old ZW transformer. The horn/whistle button works but he has no bell button. Aside from purchasing a new transformer what is the bell signal? A whistle signal is just a DC pulse . It sounds like an interesting way to use the old with the new. MTH didn't have an electrial diagram to their transformers.
