OK, how about you try to change the 6A7 tube? I never saw this effect but 6A8 are known for going very weak on their triode section (I even had a thread here many years ago). Not sure this could affect anything. But worth checking.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
