Original service bulletin for the 40-180 shows the power ratings at 60 watts, at 115 volts AC mains.
That's about 62 watts at today's average 120 volts AC. That translates to slightly over 0.5 amp of current draw. I'd use a 3/4 or 1 amp slo-blo fuse. A fast-acting (non-slow blow) fuse may nuisanse trip with turn on spikes from the power transformer.
