Reply to "Swapping sound boards from one Legacy diesel to another?"

Thank you Pete and John for the responses.

I took the respective boards out of there plastic holder and checked the Lionel part number. On the PRR U28c, the part number is: 691 RSL1 B00 REV 1 and on the Southern GP30, the part number is 691 RSL3 A00 REV 2. Do these have different numbers because of the sound chip used on each one or are there other difference that would not allow them to be interchangeable?

Although the pinouts appear to be the same, the Southern has a lot more wire plugged into it.

I would once again appreciate your thoughts.

Thanks,

Don

PS; I am one of those who prefer sounds that I like over prototypical accuracy. I really have not been around enough trains to know the engine sounds of each type.
