Question About Fuse Markings

On my British-made power amp, the markings for each of the PSU fuses are "T25A H @ 100-120v," and for the control fuse it's "T1.25A H @100-120v." Are these slow blow or fast blow fuses, and what does the "H" stand for? Thanks for the help.

Thanks. Any idea what the fuse voltage would be and where I can purchase them in the USA?

You can use higher than 125V, not lower.
Size is important, 5X20mm or 6X32mm?
