If it's just the G then it's unlikely to be a register mechanism issue or a voicing issue... so the question is, is it only the G? Are notes around it like F, F#, G# and A completely fine?
It's still possible that for you, a voicing or register mech issue will happen only (or more significantly) on the G, it's just not so likely.
One possibility is that the left hand stack isn't adjusted so the "Bis" Eb/Bb key isn't closing. What can happen is that it closes with right hand notes, so it's ok from B/F# down. It will also affect notes up to D#/A#, but G is the lowest note where this problem would affect so would be the worst, plus the lowest register is affected much less by something like this. Also unlikely to have no effect at all even on G#, so again the question is how are the notes around G?
Do you notice any problem if you press the keys with more force? Or doesn't make any difference?
The Eb is weirder because that's actually a very good note on the Buffet 1193. The G is also not an especially problematic note, at least not more than some notes around it.
>> Both tell me that triple venting does absolutely nothing to address this problem - it simply improves the tuning of the long twelfths. <<
That's not exactly true. I've made a interchangeable register vent to have different sizes and they absolutely make a difference. I don't use the stock vent hole size. The biggest difference is on the E, which struggles to come out cleanly when played in a very specific way with the stock vent hole size. Three vents might not help with the specific "voicing issue" of the F# to B area, but it can help significantly anyway. A change in the other directly improves altissimo. Whether the hassle/cost/etc. is worth the improvement is personal preference I guess.
