It would be nice if the resistor survived a dead short but it only need to
limit current to a fuse opens.
I typically use 15-20 Ohm 25W for the average 1500W amp...even if it does
2500W (-;
Dentron took a different approach with a pair of 1 Ohm 1/2W carbon in
parallel which appears to be a bit dangerous if an arc developed.

Ten Tec 425 Titan uses a single 10 ohm, 25 watt ohmite wirewound.

That is for a glitch - the resistor limits the current in the even the
tube
(or whatever) arcs and dumps the B+ to ground. The caps will discharge
through that resistor.
I went through that sourcing a couple of months back. Check out the
ohmite
power resistors - about 4" long vitreous enamel covered 50w, if you have
the
room. Should do the job.
