u can't "tune" a sax - it's not like a piano or guitar where u can just give it a little twist and it gets sharper or flatter. But every sax does have it's unique harmonics...even identical make & models will sound a little different. What CAN be done is adjustments of some of the tone holes. But only limited. On every sax I play (cuz all mine are old horns) ...they all have their notes that are a little off..and I "lip" them either up or down to stay in tune (a good ear helps...and knowing your horn). I think one of you posted elsewhere about a re-pad ---just have the pads checked for leaks. if it's an eighty year old horn...i'm sure some of the leather has worn. Just make sure the pads all seal with no leaks when pressed...and make sure all the springs re-open the keys when depressed (with no sticking). So many moving parts...don't know how those repair guys do it so well.

Hi from Tom, Sounds like you have quite a vintage saxophone. If you're new in the sax world you must be aware that technicians aren't all able to give great info. You can be lead wrong easily like a dog on a leash. If you have pad issues, you perhaps need to total rebuild. 
This can be quite expensiv. I have an Italian make saxophone from probably 1919. I've had it totally rebuil. It is great. Thing is, once the tech sets the key for precise music, it probably won't move. A tech knows, some horns move on their own (out of adjustment), usually these key mechanisms are from new saxes made in China. You're in a very different place. Try a different technician for an evaluation. He knows saxophones and can give great advice on pads, key placement and where your pads are in terms of life. Good luck, I hope this helps.
