[R-390] 4kc filter repair?

That sounds like it would be pretty hard on the connecting wires between
the transducer coil and the end terminals.

In trying to open the smaller "Y" case filters, with the shell in
a vise while pulling on the end piece with terminals and heating,
I found I usually was pulling too hard so the end piece moved too
far and broke the wires when the solder liquidified.

Not a big problem if the wires break at the terminal end
but bad news if they break at the coil.

Perhaps Steve's setup but where the filter could only move 1/2"
rather than 6'
