From experience, I can tell you that it is likely that the toroid was ruined by
the heat.  Once you heat it, the value changes, permanently, even if you replace
the wire.  I cooked a few in antenna tuners back in the 80s, before I learned
the cause.

I'd recommend you order a replacement (probably not expensive) and replace it at
your earliest convenience.  Also check with Elecraft about what other parts you
should check.  Be sure to tell them what happened, so they can accurately
estimate what issues you could have caused.
