Re: D key adjustment

To check your F vent is working properly with just the lower joint on its own (as you don't need the bell or upper joint fitted to do this), hold down both RH 1 and 3 fingerplates as if you're playing forked F and then open and close RH2 (middle finger) and check the closure of the F vent pad along with the closure of the RH2 pad using a feeler gauge - they should both close together with the same pressure.

So often this adjustment goes overlooked by some repairers who don't see many full Gillet conservatoire oboes as the F vent is already being held closed while RH3 is open, but the F vent still has to close when both RH2 and 3 are closed together (lowering RH 3 opens the F vent and lowering RH 2 closes it). The result being anything below E either becomes unstable (in the low notes won't speak easily - gurgling below low E is another unrelated matter entirely) or it packs up completely from E downwards.

With the lower joint on its own, hold it in your left hand and close the fingerplates with your left hand fingers so you can check and adjust them with your right hand for better access of all the adjusting screws.
