After going thru all of the search results for bias setting, I did not find (or just overlooked) the answer this question:
Why did the original Dynaco Engineers set the MK3 bias to 70ma per tube and the ST70 to 50ma per tube?
We all set the bias a lot lower these days but they must have had a good reason.
One thing I was thinking it kept both tubes conducting for longer periods as power draw is increased.
