I also suggest adding another fuse to protect the whole set.

Bob,
Thanks for the quick reply. The TV is rated at 150W or 1.3A. Less the 600ma filament string gives me .7A through the Fusistor. If I'm reading your reply correct, I really don't need a Fusistor, just a fuse upstream of the filament tap off....right? I could easily relocate the filament tap off to the downstream side of a fuse.
