I have a Lionel Southern GP30 (item number 6-82141 from 2014 vol 2 catalog) that I really like the look of but despise the sound of. The hi-pitch whine grates on my nerves like chalk on a chalk board! Therefore I almost never run it. I have an earlier Legacy diesel ( PRR U28C, item number 6-38415 from 2012 vol 1 catalog) that I like the sounds of but never run because it is not a railroad I tend to run. I would like to take the U28 board and place it in the GP30 and place the GP30 board in the U28.
I have the shell off both and the board seems to be identical except the U28 chip is labeled u28c u30c and the GP30 chip is labeled 6-82141.
Has anyone done this or is there a reason that it would not work? Are there actual modification to the later board that wouldn't be obvious?
i would appreciate your thoughts.
Thanks for the help,
