Finding the bad tube
After due burn-in, my Schiit Freya+ was really singing in tube mode with its four big old 6SN7s. Then one night the sound just went flat. Visual inspection (not that my eyesight is so acute) gives no clue.
Well, I was ready for a roll anyhow. But would surely like to identify and dispose the bad egg before doing so. Is there some simple way of outing the culprit?
