Yup, compared to a 65 year old cap, a 25 year old cap looks "new." Most likely still bad or about to fail. You'll have to undo the hatchet job, but take plenty of pictures.
I'd replace the carbon resistors as well for long term reliability at the same time you change the capacitors. Easy enough and inexpensive.
