Not in this case

While it's true that ARC pushed 6550 output tubes in the day, the LS27 (like my SP20) is a hybrid with the 6H30s serving as cathode follower buffers for the JFET front end. And the tube itself was designed by the Russians for military duty.

It's a darn rugged tube. Arguably, the most knowledgeable expert on the use of the tube is an inmate here who pioneered the use of them in audio electronics. Search for posts by Victor Khomenko of BAT.
