Here's an obliquely-related related anecdote: It has been 2 years since I put a pair of "quasi-boutique" 6C33Cs in the boost position in my ML2s. I know, I "should" change them to regulation, just to be safe; but now I have become morbidly interested to see just how long they will last as amplifiers. I cannot say they "sound better", or anything like that; and of course they need to be re-biased regularly, like any garden variety Ulyanov. I would deem the longetivity a fluke, but both of them are still going strong (...knock on wood...). While I'm thinking about it, I should also mention that (as always) I cleaned the pins carefully and greased them lightly prior to use, and I may have pulled them for cleaning and re-greasing maybe twice since I first put them in.
To be clear, I do NOT recommend anyone else leaving any 6C33C in 50+ Watt boost position this long, and if you hear "popping" from your 6C33C, pull it and toss it immediately.
