As an aside, We are working to create an addendum that illustrates the minor wiring changes required to use a Protosound 3/2 Stacker in a 4 motor application (such as a lead powered A with a PS2 board and trailing powered A with a PS2 slave board). (This addendum will also apply to any tubine with 4 motors.
What I’m saying is that if the factory installed PS2 5V or 3V board in the lead unit goes out, you can use the stacker to replace it AND keep the PS2 Slave board (no need to spend 2x the money to repair a n AA or ABA set with a bad lead powered A board.
We’ll hopefully have this completed around the time the boards begin shipping in March.
Thank you,

I've replaced a PS2 5V & PS2 3V boards in diesels that have a slave board in another unit with a PS32 board with no issue. Just load the correct chain and sound files and it's good to go. No wiring changes necessary. So for your average ABA diesel set a PS32 board is drop in.
