The LM337 applies a regulated voltage to the cathodes. Because the adjustment is between ground and B+, variations in B+ are transferred to the regulated output, helping to stabilize current through the tubes when B+ varies. As stated above, this is all explained in great detail on Dave Gillespie's site.
