So, I know this may sound stupid to a number of you. Please, if you don't have something constructive to say - just don't even comment. Thanks.
OK - so I am well aware that the chugging sound and brakes sounds in PS1 steamers is voltage activated - but, there's got to be a bit more to it, because if you disconnect the motor from the board, you don't get any chug whether or not the voltage is up or down. So, is there a feedback system in Proto-Sound that only allows the chugging to fire when the motor is drawing amps? What's the secret here?
The reason I ask is because I'm thinking of upgrading my Big Boy to PS2 or PS3 - I'm already missing the smooth slow steady speed control that PS2+ offer. But, I absolutely love the old chugging sound the Big Boys had in PS1. So, my thinking is to keep the old board and put it in an auxiliary water tender (and just wire straight up to the coupler) or something I can trail behind big boy so I can still make PS1 Big Boy sounds when I want to....but, without the motor attachment, I'm SOL on the chug sound right? ....What if I put any old can motor inside the water tender with the board and just set it sideways to freewheel discreetly so it could extract the chug sound when running conventional. Would that work?
Just an idea. Thanks for any positive feedback.
