Several months ago I posted a parts list to upgrade my Legacy E7 powered B-unit with sound. All the parts were available at that time, but now the specific Railsounds 5.5 board for my loco is not available. So here is my question:
There are other Legacy E7 Railsounds 5.5 boards available. These are for the A-unit. If I were to install one of these boards for another RR (B&O, etc.), can all the other sounds except the sound for the prime mover be shut off? Specifically the crew talk? I want horn, bell, crew talk out of the lead A-unit only if possible.
I have other B-units but they are from other manufacturers where the B-unit came with factory installed sound.
