Re: "leak" that won't go away
All of the above, and: have the neck piece/reciever connection checked. Have the octave key pip seal checked. Have the side keys checked with a feeler gauge. The seating on these keys is very difficult to see with a leak light. Have the spring tension on the side keys checked. If the springs are too weak, you can blow these keys open, creating a leak. Have the F # key pad checked. It's easy to knock this key out of alignment. It sounds as if the leak is located somewhere in the middle of the horn..articulated G# is a bet..F#/G# adjustment, etc...and yes, bow to body joint. Leaks in the palm keys can cause this kind of problem. Make sure your tech. is using a feeler gauge along with the leak light. If he won't, find one who will. You cannot find every leak with a light. If possible, find a tech. who plays the horn well, he'll be able to tell . Good luck. Hey, Cuber..how ya doin?
