my wife purchased a flugelhorn on ebay for very little money. It is a Selman model. She plays very little, mainly just practicing. The issue is that even though the instrument was new, the valves on it are sticking. I took it to the local Music & Arts shop, which sent it away for repair. It came back without being repaired as the shop said they weren't able to find parts for it. I realize this is a cheap horn, but I want to get it working for her this Christmas.
Is there anything I can do to fix it myself? We have tried valve oil to no avail.
is it worth it to get it repaired, or would there be anything in the $150 range that I could get her instead? We dont have much $$ right now so any suggestions are appreciated.
