Modern Chinese 274B tubes are 5U4GB tubes with 274B written on them to cash in on the "mystique" of the Western Electric 274B which very few people have heard.
Buy a high quality US made 5U4GB from the 1950s or 1960s for long life and good sound.
Follow Ups:
1960s Tung Sol 5U4GB will give a WE 274 'a run for the money'.
The 274 was more of a 5R4 anyway. IOW, not much peak current capacity, but able to tolerate more PIV. Check the specs per the usage, and if it is a modern 'approximation' use some caution... :)
cheers,
Douglas
