This voltage is related to AGC, not ALC.

My impression is that people worry too much about this. With all
components exactly on value this voltage is only achievable with R1 at
the end stop (I can't remember if it is just achievable or just not
achievable). What really matters is whether or not you can get a
sensible AGC threshold within the control range of R1, which you can
only do once you have the whole receiver.
