    Because it's basically two single ended amplifiers wired together bridged (differentially) the DC components cancel, by and large, with the help of a DC offset trimpot. I monitor this roughly monthly, or as the mood hits, or if I see or hear a need to do so. After experiencing a few tube section failures with NO audible results (NONE) I'm convincing they're bulletproof. After a complete retubing, I find no failures in over a year of daily usage, with 16 output tubes, a pretty good record. Ralph describes the basic circuit best.
