Don't have the specs for you, but these guys helped me when I needed flat springs for my Conn soprano:Is One able to purchase the above items on-line?
Trying to get the job done myself . I live in the UK and am fed up with my horn never getting done 'right'. I think I can do better myself and not have have to deal with the ********.. Any experienced repair person will have a junk box that may include a spring of appropriate size; .
As I said... contact them and tell them what you have. They'll make suggestions accordingly.Thanks, have been on their website but nothing stood out in terms of 10m flat Springs for Tenor Sax.
Not enough info to say anything for sure (and the only real way to be completely sure is to check it), but if there is a sudden change from low C to B, and low C# is also problematic, it could be something simple like the right hand stack keys not closing the G# (which is opened by the other left hand low levers).I re padded the three other pads myself so I saved a bit of cash there. My horn is still leaking but works from bottom C to the top. Oh well.
