I assume the resistors and capacitors in the preamp have a 5 or 10% tolerance. So if a few of these are "off value" in the same direction (but within tolerance), then you can get a different tone. Five percent here, five percent there; it can add up.
Testing this would require swapping the preamp (or preferably the entire control plate), which is a pain. It would scientifically eliminate electronics as a possible reason...
Sure. Tolerances add up. But if applied correspondingly onto a hifi system or maybe a bass amp that would mean that even equal systems show big tonal differences. But that's not true. (Plus, a hifi or amp is a much more complex thing than a preamp)
I'm sure that it makes absolutely no audible difference if you swap two preamps.
