    Hey all -

    I wonder if anyone can help me out with this..... I have a King 2007 (pre-UMI pro model) which I love, but the valves show some disturbing behavior.

    They work very well, but there is significant side-to-side movement in valves 2 and 3.

    Compression is good and the valves show no significant wear on the pistons. However, there is about 2mm or more 'wobble' side to side.

    Do they need rebuilding? I hope not: I've seen prices of about $400 for this, simply out of my budget.....:dontknow:

    Any advice appreciated!
    Thanks
    Bruce

    I wouldn't think the valves would need rebuilding after only 2 or 3 years unless it was an off beat brand. You said it has good compression. I wouldn't think you would have valves that loose and good compression. Maybe just the stems are moving. See if they are loose. Does it have a warranty? If it plays good in the low register, and the valves don't stick, I wouldn't worry to much. Good Luck, Bobby

    Maybe the valve guides, which probably are plastic are worn through. That is the most common problem I see when valves wobble if there are no other signs of wear or tear.

    I think that we need to keep this "valve wear" thing in perspective. I have a 1911 Holton cornet with essentially NO compression. It plays wonderfully, is in tune and has those slot thingies that many players quote but do not understand. There is a double C on that horn too.

    So what I am trying to say is that "tight" valves are good, but the trumpet does not fall apart or kill the player when they are not.

    If the action and compression are good, no worries!
