That is a very nice looking TOM. The replaced connector is for the GI circuit on the power driver board, and is not unusual to get toasted and replaced even on a very low use game such as this (mine was similar condition and had to replace it also). The reason for the power driver board itself being replaced could be burnt pins from same connector that someone didn’t want to change, but is anyone’s guess. It’s not from battery acid damage though, as the batteries are on a different board altogether.
