I've got two Heathkit A-7E monoblocks (the ones with the ultra linear screen taped output transformers and phono pre amp stage) which use two 12A6 tubes each as PP outputs. I'm listening to them now and it sounds awesome!
Always was curious why they used that type as an output, and not a 6V6 or some more common type for that, but I can't really complain that they did.
