Hmm, so the test circuit is using 9v and the datasheet shows running 22.5 volts to get 240 uamps off the plate and 60 uamps off the grid. but inferring from the 15v test in the datasheet your 80 and 95 are closer to to what the tubes should put out. So off hand, I would think that in terms of are the tubes good, the 23 and 33 are reading low and may be going bad.
but for your preamp purposes of the test, you want the closest two lower readings are 10uamps different while the higher are 15, which at first glance is your lower readings. But I do not like the low readings compared to the datasheet.
I do not think in this design it make any real dirrence, and I would use the higher draw as they look "healthier", plus the designer makes a point in stating for "Tube Purest" Which is kind of a slam to the HIFI community.
NOTE before I would call the two low emission tubes bad.. I would build the same circuit but use 15v, and use as close to 1.3K resistor for the heaters. you should read close to 100uamps +/- 10 - 20%, There are better designs to test this, but for a quick check, it would be my first attempt.
