Because you have to replace all the electrolytics and paper caps, there were like maybe 6 micas left. They have been known to got bad. So why not replace them too? There cost isn't too much either. Also it eliminates problems down the road. Say a mica still works, but then several hours it decides to quit. Then you have to go back and pull the chassis, trouble shoot the problem, replace the mica, maybe do another alignment, then put it back together. Seems the risks and rewards aren't worth NOT replacing the micas. Also when replacing the paper caps, most of the time there is a resistor on the terminal too. So you pull the cap lead off, why not the resistor too?
As far as the resistors go, what do they cost? Maybe 14 cents each? Some you have to lift 1 leg to measure. Half way to replacing it already. So it measures on the high side tolerance and you don't replace it. Same situation as a mica.
Also this is a hobby to me. I enjoy replacing those components, cleaning, painting, polishing, etc. This way, when I'm done with a restoration, most of the troublesome parts have been replaced with a modern (re: a better) component and I can expect a long life of excellent use.
I know some guys do a "restoration" by replacing just what is needed to get it going again. To me that is like putting 2 gallons in the tank when you can fill er up! But I'm not criticizing them it's just what they do. This is how I do my restorations. Everybody sees this hobby through their own set of eyes and gets out of it what they want to. Neither is right or wrong. But different approaches.
