I'm actually firmly in the camp of wholesale capacitor replacement. The reasons I didn't here was that the seller had already fired it up and it makes for a more interesting youtube video series.
I started going through the chassis more thoroughly last night and was surprised at how far out many resistor are. Some as much as 5X the specified value. Those will all get replaced along with the remaining paper, electrolytic and mica caps in the audio IF cans.
That would be a 30 pF and 35 pF cap in this revision. They are exposed to the air and can develop SMD.
