Help me Tuba Conn 15j
Posted: Fri Jun 28, 2024 5:12 pm
Hello, good evening, I wanted to know how I check if the valves on my conn 15j tuba are original. Does the number on them need to be the same as the number engraved on the machine? Sorry, I'm new to this area. Only one valve has the same number that is engraved on the machine, the other two are not the same as those on the machine. Does that mean the other two are not her originals? Are they from another conn 15j tuba?
