I am not a life-long tube designer and so I do not keep the tubes' datasheets the way I keep semiconductor ones, and so I have to go by what what I find, and so fat what I find has the words "maximum" and "40 uF" next to each other.
I saw one sheet showing 40uF undet "typical" but then it did not show maimums.
So, if you produce a datasheet that says explicitly "maximum 50uF" I will agree with what you say.
Meantime, here's another one for the same tube I found.
And....speaking of "several decades of operating like this", we do not know how many time this tube was replaced.
PS. I am not saying the tube will immediately go up in smoke because of 50uF. Or even 100uF. It might last for years and, given today's "once in a blue moon" operation, might live forever. But to me this is a wrong way to do things. Even if it works.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
