When I restore a set, I replace only what is necessary: electrolytics that fail to restore, paper capacitors that have a high DC potential across where leakage will cause a problem. I leave the resistors until I fire the set up and the analyse the performance. Eg narrow width could be the dropping resistor feeding the horizontal oscillator. I have lots of new old stock carbon composition resistors I replace the originals with.
And I try to wire it as if no one has been there since manufacture. (The only difference is the capacitor appearce between the old paper and newer metal film. Resistors look the same except for the added or improved tolerance band). Even if the resistor is slightly out of tolerance, so long as it does not affect performance, I will leave it.
