"Restoration" vs "Preservation" vs "?"

[VTVM]

Since I think that repairs are a legitimate part of a set's history, and usually find a mix of tube brands and one or more post-manuafacture capacitors, I usually don't worry about restuffing all the caps, etc. If the set is a particularly rare unit or nice candidate, I lean toward remaking or restuffing caps, resistors, and using cloth covered wire.

I often roll metal film resistors in epoxy putty to get the appropriate external dimensions and shape. These are smoothed and repainted. Since I do not know, specifically, what this does to the voltage rating and wattage, I use a considerably higher rated resistor than is otherwise needed. This usually doesn't seem to present a problem for me because of the tendency for these modern resistors to be smaller for a given set of ratings.
