I’m familiar with 12ax7’s and the like, compactrons are new territory for me.

It's probably two or more sets made into one!
I scrapped a 1970 set that had a 11WP22 from new, so the 11SP22 was from an earlier model.
Compactron tubes are multi-section tubes that are really not that different than single or dual unit tubes that you're familiar with.
Example: the 6AC10 is like a triple unit 12AU7. Looking at the schematic will help you understand.
