That helps a lot. I'll try the relay. That sounds like a very cool effect.

Also: it finaly dawned on me that the J1 connector the manual is talking about is the J1 on the "edge" of the Bachmann board, not the J1 that is in the middle of the board that the Aristo Revo board plugs into. I was not wanting to solder to the Aristo board.

The chuff is working good.

About a month ago I bought a new Bachmann 2-6-6-2 Saddle Tank. I've installed the AristoCraft Revolution Remote Control Receiver and now have the Phoenix P8 Sound system to connect. I have everything connected except the Chuff sound. I've seen the article with the 2n2222 transitor circuit for the K27 Chuff.... But, how do I connect the to the Chuff sensor of the 2-6-6-2?  Anybody know???
Thanks
