| Does it change with the voltage/throttle? ( I am assuming you are using DC) Do you have a pic of the circuit?

I'm sure it's just a primitive white noise circuit that is turned on and off by contacts on one axle closing a set of wipers once or twice every revolution. That's the way they put sound in the early Heavy Hauler G scale 4-6-0's, and the circuit was powered by a 9 volt battery. It was bloody annoying, to be honest, with no volume control. It should also be four chugs per driver revolution.
You have one in a PT tender, so I assume you mean Powertorque? Someone installed it in a Tyco 0-8-0 or 2-8-0?
