My father bought a Philco 37-650 for Christmas 1936. It went about 2 years when the first filter condensers went bad (opened). It (or they) were replaced by dry electrolytics, and I never had known that the originals had been wet types. Right around that time, wet electrolytics were on their way out.

Cute tale: I worked in a radio shop in 1944, on the bench, and one of the guys told that he'd been on a service call in a home with a console set that had a tilted panel chassis. The chassis was mounted in the cabinet on an angle. As with many chassis designs, the filters were mounted along the back of the chassis. One or more of the filters on this set had heated up in a failing mode, and blew the top off the can. There was a big spray of juice up the wallpaper behind the set. I guess it scared the slats out of the owners!
