Thread: John Packer Valves

  1. #11
    How new is the horn? Have you cleaned the valve and the cluster thoroughly after the horn arrived? Also what valve oil are you using?

    I feel that I've seen this issue before (mere deja vu?), but I'm try to recall when it was and what was done to resolve it.

  2. After a full day of trying to figure it out. I managed to change the felts and this was the outcome.

    Still waiting for the video to render, but I'm anxious to see it.

    The bounce you get on the downstroke I THINK is your own doing. You finger should push the valve all the way down, and if you do that the valve can't bounce. In any case, you WANT the valve to come back up as soon as there is no finger pressure.

    That doesn't really look any different from before. I didn't think it had anything to do with the felts anyway. To me it looks like the springs are too weak, just like another poster wondered. This is why I asked if the original Packer springs were doing this or if it was when the change to SM springs was made. IF the SM springs are for Baritone or Tenor Horn instead of Euphonium this could possibly result in the springs being too weak or too short. But really, bottom line, this is a brand new horn and you are doing way too much on your end that could possibly void any warranty protection you enjoy for all that money spent. Contact your dealer pronto and let them sort things out for you?

    I think that looks a lot better

  6. I have a JP-374ST and use mead light springs. After cleaning my instrument I have found that the springs vibrate while playing. The diameter of the spring is too small and is not seating but sitting on top. I've tried putting tuba springs in but they are too big. What size springs are in this instrument?

    Have you unscrew your vales, take it halfway out of the valve and put it back in? That's to try and re-seat the springs. Mead springs will not sit as nicely on the JP line since Mead springs are tapered while the bottom of the JP has a raised part in the middle. But if seated properly, it shouldn't vibrate. I personally used Mead light springs on my JP274 without much issues. I've experienced said vibration before and re-seating the springs properly fixed it for me

  8. Hi! I'll try to unscrew them halfway and place them back in. Do you happen to know what size springs the jp uses?

    See Dave Werden's helpful video tip on reseating a noisy valve spring:

  10. I'm pretty sure that there isn't too much variation (any?) between brands of Euphonium springs with respect to their overall diameter. They are, for all practical purposes, interchangeable. Tuba springs (as you found out) cannot be used in Euphoniums. But between different Tuba models, most anything sold as a 'Tuba Spring' is going to work. That said, I have found that since the JP line is 'bottom sprung', if the spring vibrates, unscrewing the bottom cap several turns and/or taking the bottom cap off completely and re-seating the spring before tightening it again will almost always cure buzzing. But the sure fire fix (that I haven't tried) is plastic coated valve springs (Yamaha?).
