Vinzer;
You are correct that it was originally wired that way and has an insulated cathode, but for best protection, B+ rectifier tubes should be on a separate filament winding, especially where there is no fuse on the AC input. If there is a fuse then I might trust it. I have seen such tubes short cathode to filament and if that happens and there is no fuse, the transformer goes.
