That will work. A caution on fusables. At an RCA seminar a few
complained that the fusable always opened & not the fuse. TRUE !
They said its because the fusable protected the fuse. TRUE !
Bottom line is when you turn on a set there is a very heavy
current draw to charge up the filter cans. The fusable limits
that & lets the caps charge slowly. If it wasnt there the fuse
would soon fail. It also acts as a fuse, I have only seen them open
with a shorted rectifier or for NO reason, just age. Sets with
them rarely blew fuses !
Last thing is its important on solid state sets with kick-start
circuits. They depend on the slow & proppor rise of the B+ often.
