Hi Tomi!
You have a lot of answers for your own question, are these things you do not want to do?
It could be that some resistiors drifted off value, having a much lower resistance than the official value.
Maybe the tube is bad, but I think you tried that already.
Changing to a 12AY7 might help, or a 12AU7.
You could try changing RA.
