The linked article is helpful, showing how an old radio can sometimes come to life without replacing caps but extrapolating to state they don't contain electrolytic capacitors is inaccurate. Even the photo in the article shows a big silver can that's a classic electrolytic cap:
Maybe a case of communication breakdown?
Here's a copy of a Sam's guide for a 72 Pontiac AM/FM showing 17 electrolytic cap part numbers:
If you're interested, this is a good real-world article on the reliability of old electrolytics:

When I opened a radio I bought from a forum member, here's an example of what I found before I even powered it up. This was a 40+-year-old electrolytic that is obviously bulging. Had it failed? Maybe not, I didn't have an easy way to test it.. but it wasn't healthy!
This is why I personally would not pay "restored" price for a radio that had not been serviced by a pro.
