Does anyone have a pair of crossover coils for the Wharfedale W-90's?
Thanks,

What happened to the old ones Eddie?

The crossover tabs got loose from abuse. Over time the coils fit loose in
their tabs. I have tried to solder them. I don't know what material the
coil is. I've used flux but the coil simply won't solder. Any advice?
Thanks,
Eddie

The usual material for coils is copper wire covered with a particularly
tough varnish. It is usually necessary to sand off the varnish in order
to solder to them, and if the wire is heavy (16/14/12 gauge) then an
old-fashioned soldering iron may be necessary.

If the coil is an air core (wound over a wood or cardboard form) then
duplicating it requires duplicating the number of turns around an
identical form using wire of the same gauge. If the coil has an
iron/ferrite core than you'd probably have to reuse the form.

This would be routine stuff for a radio repairman ca 1960, when these
were built. I owned W60D's ca 1963, so I have severe doubts that
there are a lot of spare parts around, but there may be a retired
service tech who can help.

The wire is coated with an enamel or varnish. Scraping and/or sanding
the coating off will enable you to make a good solder joint. Tinning the
wire before you solder it to the terminal will make the job easier as
well.
