    Thanks to NYTC I've improved the action on my Bundy Bb Trumpet. I replaced the current springs with a HIGH SPEED VALVE SPRING for Trumpets Model: VS 03. Less finger pressure, and smoother, exactly what I was looking for. I'm hoping the same spring comes in the type spring that fits over the upper barrel. I will be contacting NYTC for them. By the way, NYTC let me know if you have the above model spring that fits over the upper barrel size: approx. 7/16 diameter and approx. 1 1/4 length. Let me know what I owe you...............thanks, crow

    A 50 HP shot of nitrous...I hear there are plans for a turbo system, 10 psi of boost.

    I hope the valve casings are "built"

    On a serious note what makes these faster. Are they stiffer springs?

    The springs do not need to be "stiffer". Newer springs are more resilient. Fast can be achieved by thinner spring wire with higher tension. The high tension makes it fast and the thin keeps the pressure needed down.

    If valves hang during a concert, you can help yourself by "stretching" the springs. That will not solve the problem, but give you temporary relief.
