That is roughly 3% and 1% respectively of the B+. Not horrible, especially compared to the late 20s and early 30s radios that these replaced, especially those with 71As, 45s and 47s (filamentary cathodes), and rather small filter caps. +1 on using the 50L6, switching the hot instead of the neutral and using a polarized plug. Usually no need for a fuse. The rectifier filament serves that purpose. Dunno if a fuse will blow before the rectifier.
