G# on Keilwerth tenor has an extra lever across hole.Underside of lever has a flat spring flopping around. What does it attach to? I tried putting a photo but I cannot figure that out either.

That is the spring that J-K adds to the mechanism to provide lift to overcome the sticky G# key.

I don't see that it has any spring lift....as I manually move keys it doesnt seem to "spring" anything....know what I mean?

In the pic that EgilF. posted, that spring is rotated in line with the key. You may need to remove the key to tighten the retaining screw to keep it from flopping about.

1) Push down the #G-key and finger a F: without the spring the arm is loose.
2) If you play a f the spring makes the #g-lifting arm stay up, without the spring the arm is loose and falls down/up when you are tilting the horn.

My alto has the same:

B&S do this same thing but with a different spring type. It wont appear to do anything until the G# sticks when you are trying to raise it, at which point it will contact at point "B" and apply pressure to lift the G# cup. The spring is there to keep it tilted the correct way (towards "A") rather than flopping about I think.


From Steve Howards review...

"In normal use, and with a working G#, the arm does nothing at all - but should the G# stick, the lever pivots on the stuck G# key cup and makes contact with the Aux.F key cup. Once it does this it tries to force the Aux.F key down - in effect using the spring of that key to boost that on the G# key cup and supplying the upward force at the pivot of the lever."

Very interesting. My Keilwerth has the bar, but no spring. I was just looking at it today and thinking how worthless it is.
