I should dissect the faulty resistors to give an answer to your conjecture.
By the way, by replacing them with 10W ceramic ones I think that this problem will likely never happen again.
The 6SN7 driver is biased to have enough room before saturation, so I do not think it might be the culprit.
Thank you for your comments.
Best Regards
Luca
