Have recently bought a Yamaha YTS-23 as a back up tenor. All is fine bar the F# key. It is not lowering over the hole without considerable force. I do not mean it is leaking only to be spotted by a light, I mean it is clear that the key is not lowering enough. Around the entire whole there's a mm gap. Is there an easy way to correct this? The pad seems fine, new almost, so am wondering if one of the rods needs looking at....
Have never repaired my own saxes apart from small jobs, which this well may be. If so, can someone point me in the right direction?
Many thanks in advance.
