So I have had this horn for a while, and really do enjoy playing it. It is an old Conn 15J. Ever since I have had it, you have had to hold the lead pipe on while playing the horn! This can be quite annoying. I am wondering if this is something I can simply goto the nearby repair shop with the horn and order a new one, or am I stuck with my current situation. Below are a couple pictures of the horn, it has a thumb screw where the leadpipe goes into the tuba body, I don't ever mess with that since there is a smaller diameter piece of metal sticking out of the hole that the current lead pipe sits over pretty well.. if you use one hand to hold it there.

Any suggestions welcomed!

Thanks guys..

Boy, that's an attractive solder job!

But, to answer your question, yes...this should be easy for any competent brass tech to fix.

I like those horns. Both the Conn 12J and 15J are pretty good players. Unfortunately, what is now called the Conn 15J is actually a King 1140 and the parts won't interchange. I've made several of the pieces like you need from odds and ends in my junkboxes. I don't remember exactly the screw size in the piece that is still attached to the horn, but it should be pretty easy to figure out by visiting your local hardware store. I think it's a common size... like maybe a #8-32 or close to that. They'll get a kick out of it when you take the horn there to try screws. Once you locate a screw, you can fashion a piece of metal to hold the leadpipe against the horn.

Also, unless you plan to put the marching leadpipe back on, you can just solder the concert leadpipe to the part that's still on the horn.

Both thumb screws are on the horn.. and actually where that duct tape is the entire bracket is there, The problem is the leadpipe on the horn is a smaller diameter then what is meant to be there I Think, so the bracket on the bell doesn't secure it in place.

The biggest problem I have is how the leadpipe hooks to the horn, is this how it is suppose to hook?(the leadpipe goes over a small pipe out of the tuba) or is the end of the leadpipe suppose to be more like a tuning slide where it slides into the horn and then is tightened?

Thanks for the replies! I like my sound with this horn, and its a very free playing horn..

Oh... I think I understand now. First, the bracket that holds the leadpipe to be bell is probably just bent. It's just a half-round clip that has a screw through it and holds the leadpipe agains the bell. On the other end.... that small pipe that you describe is supposed to be soldered into the ferrule on the leadpipe. It then slips into the receiver on the horn and is held tightly by the pinch screw. Take it to your local repair man and we can get you going. It sounds like you don't need any parts.
