I hate it when I open up a cosmetically well restored piece of 1932 electronic equipment and find it full of orange drops and metallic film resistors.
I have the opposite reaction. If I see a point for point replacement of weak components with like value, and they took great care in doing this, my heart sings - I have a radio that isn't going to burst into flames and will likely work when I plug it in. But I never did the really old radios with the pretty components.
But in many cases, it is not a matter of preservation. I simply don't want to waste my time and resources replacing components that are still performing at or near original specs.
This is true. In all restorations, you balance the risk and cost in performing the work over the benefits (improvement in performance, looks, reliability). I now check all the resistors and replace as needed, it takes little time, over the risk of burning up a hard-to-replace IF coil or bandswitch when 'debugging'.
