I only replace tubes if they test really weak. Even the borderline ones I keep.
I test them all, never relying on "maybe it's good".
In the current radio one tube has shorts, and two are very weak, so I bothered Bob Dobush. Speaking of which, I still have not received the tubes, so he gotta be looking for some.
I am yet to see a good paper cap. They are 100% leaky and 100% go up in value.
American ones are typically 50-100% up in value; the German ones I replace in Grundig are 300-400% up in value. Superbad.
Resistors....if they are not more than 10-15% up, I keep them, after all if they survived well, why change. More that that - I replace them.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
