Thanks in advance for your input.

If it was me, I'd just toss them. But.....

What's wrong with those instructions?

They're OK - I think I need a little more info on how to test
crossover networks because I think at least some of them are bad -
i.e. the speakers will sound connected to an amp directly but not
when connected to the crossover network in the box. However there
were some useful bits.

Capacitors in crossovers are probably the part most likely to fail, and they
should be easily replaced.
