Now that we have a bunch of sources for the part,
I might be more inclined to experiment.

Resistance of a small incandescent bulb can go up a factor of 10 when it gets hot: 
That or a fuse would be easier to replace than an 8 pin dip.

I wonder if a small light bulb. like the old standby #47 could protect a speaker short.

Maybe some type fast lo-mass fast Thermistor?   Something that has small resistance, but goes up quickly with a short.

Just thinking crazy.
