First, as to the resistors. They are 5 Watt, Ward Leonard wirewounds. Very rugged and reliable. Vitreous enamel coated, which will not burn or smoke.
You probably only burned the dust off them! I would definitely leave them as is.
Regarding the stereo light. When you switch the selector to FM mono, it should ground 4D ( TP 402 ) on the multiplex board. Doing this removes base drive from transistors Q404 and lamp driver Q406. If you ground terminal 4D, the stereo light should go out. If it does not, then one of those transistors is probably bad.
Check the voltage at 4D and confirm it goes to zero when switched to FM mono position.
