Oddly enough, that is the one tube that I replaced. There is a GT in there now, but everything runs cool. I learned long ago to check for overheating components. From time to time I remove the chassis and power it up to check things under there.
Anyway, this is not the only unrestored and working piece that I have. It is I think the oldest, but I have several 40s-50s radios and two TVs from that period that still work. A lot of it has to do with how much a set was used in the days when it was in regular use, and then how much dormancy there was, or has been since. I try to power up everything that I have at least once a year and just let them do their thing for maybe an hour or so. Now for long term or heavy usage I would feel better with new caps. As a tech, I know that getting the old caps out is the way to go, but a part of me loves the unrestored electronic miracles of sorts.
