What Unusual SET tubes you've tried & liked?


I'm hungry to try something new and different and want to build a SET headphone amp. Does anyone have any weird and wonderful tubes they have tried successfully used for this type of project that sound decent and are still available

They are exceedingly uncommon/hard to find but have you considered a PX25?  Similar to a 2A3, Art Audio produced a 5w power amp for years using this tube and it is an interesting middle ground between a 300B and 2A3.
