Check the premier alco PAs. I like to have a ABBA set, one B looks a bit off for me.
With the all power built into a single unit, it seems the railroads ran them as A-A or A-B-A sets. Cannot recall if I've seen a regular assignment with four of them and the last image is the only one I could locate. Not sure if it was a common event or not , it says it was taken in 1966. We don't model the worn out era so that is of no interest to me.

Since there were so few PB's built compared to the PA's that is another thing against it from a manufacturer standpoint. Don't forget that on a layout an A-B-B-A set of ALCO's is around six feet long without a train and many (most?) simply don't have the space for it. Good luck in your search, you could always change the number yourself.
