What are fuses used for?

It is also possible if you have newer gear there maybe NO "user" accessible fuse to change.
There has been a trend to just solder a fuse internally on a board.

Obviously not something you can just switch out quickly and easily.

Some even more enlightened manufacturers have abandoned fuses altogether in favour of circuit breakers.

I think I’m going to be a flatearther on this one.
It seems like too much trouble.

rvpiano,

I appreciate your candidness and respect the decision.

OP
Probably a very wise decision... Lol.
One more item not to fret over or spend money on!
