11T crossover question

I'm putting new PolySwitches in my 11T (Thanks Ken!). On one crossover I noticed one of the big rectangular resistors has a huge brown spot in the center, like it got very hot. Is this normal, or does it surely need to be replaced. Maybe this is why the switch was opening.
I can't check it with an ohm-meter unless I remove it, since it is parallel with an inductor, I think.

That one is cooked, time to replace.Political Correctness'.........defined
"A doctrine fostered by a delusional, illogical minority and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a t-u-r-d by the clean end."

You might consider replacing it with a Mills resistor. Good luck and have fun.:)JC approves....he told me so. (F-1 nut)

That would be ideal, but then if it were me I'd replace them all (in both speakers) with Mills and then why stop there. Rebuild the whole x-over. It seems by the pic you have to remove the caps on top anyways to get at the resistor

Why are we looking to reduce a subjective experience to objective criteria anyway? The subtleties of music and audio reproduction are for those who appreciate it.
