At least some of those wax caps are a hazard that can take your power supply out.
Some might not matter much, but all of them are bad and will check out as 3-4 times the nominal value.

I think there is not one person here who would not tell you to change them.
But if you are really trying to do as little as possible, at least change caps directly expised to B+.

# 76 and 85 for example.
However even if it works, you are likely screwing DC biasing of the tube as your DC blocking caps are likely leaking.

This is one case where it is not a waste of time.
