These two capacitors are the next ones needing replacement.The black plastic one provides some filtering of line noise and is
one kind known for exploding when shorted. I have seen many of these split wide open with shredded paper all over the underside of the chassis.
Not particularly dangerous but quite a surprise for the unspecting person who plugs in unrestored equipment!
The value is quite high, .033 MicroFarads, by modern safety standards, so I will replace it with a safety capacitor: designed to fail open
instead of shorted and of a lower value recommended by UL for this type of line filter.
The other will be replaced by a polyester film capacitor. The cord is still
somewhat flexible, but I will replace it since it is over 50 years old.
