Hi clarnibass,
No doubt that you see many more instruments than I do and see the problems I have not seen and may never see.
However, his clarinet is almost new. Old stock but practically unused, so I would not expect leaking posts or holes in the wood- not that it is impossible but very unlikely. Well, no one knows how the person who owned it before, treated the instrument but chances are she did not abuse brand new R13.
I would expect more common problems like leaking pads or chipped tone holes.
Even my new R13 A had a couple of pads that needed re-seating, and the crow foot adjustment.
But it was playable even before the above work was done.
When I said, "once the tenon(s) problem is fixed it does not come back,'' I should have said "Once the tenon(s) problem is fixed it is unlikely to come back".
My Bb required tenon adjustment twice because the tech was very careful first time and removed so little material that after two more days it was binding again.
