Regarding the tuners mentioned. the RF and IF stages determine the gain, bandwidth and phase shift for the incoming VHF signal. The detector stage converts this to a "composite" audio signal. As has been mentioned, these did differ between units. The multiplex stage figures out which part of this composite should go to the left and right channels. With few changes (updates?), most of the Mac multiplex stages were identical. The following audio output sections were also "changed" (they had problems with the multiplex indicator).
Not to mention that parts (like tubes / capacitors) were undoubtedly different (types / manufacturers) between the models.
So they should sound different. One better than the other ???? Certain manufacturing runs of one model?
Yes; and the 10B and last Tandberg (don't forget the Scott 4310) are no "slouches".
Let's appreciate that this ancient technology still can sound GREAT - "Improvements" in broadcast technology not withstanding.

FWIW - the best I've ever heard are still the REL and the Wonderful Rhode Schwarz
