Don't go completely nuts in hunting down bad resistors until you have swapped out your output amplifier tubes with known good ones. 42's are notorious for intermittent frying bacon sounds- I've got a box of noisy ones. Noisy 42's can sometimes be used in the audio driver stage, but never in the final stage.
