For example, while the EL84 has a current capability of 48mA, it has a plate resistance of 135,000 and a mu of 418. A 6SJ7 can't pump enough juice at only 3mA.

The pentode is not all that important, it just needs to supply current. That is why the transistor sounds about the same. Alan piched through a bunch of tubes befor he landed on the 6AC7. While it can only supply about 10mA, it has a sky high plate resistance of 1,000,000 and a mu of 9,000. I would only change the tube if you needed more than 10 mA.For example, while the EL84 has a current capability of 48mA, it has a plate resistance of 135,000 and a mu of 418.
