I spoke to one of the engineers on the floor at NAB, and he said they intentionally chose standard off-the-shelf power supplies and tried to do the same for any component possible. I've seen Orban audio processors from 30+ years ago still in service, there are still companies out there that favor standard, repairable parts, especially when you have an audience of engineers who favor not having to drive out to remote studios or tower sites multiple times to get something fixed.
