Hello,
I recently picked up a secondhand Harrelson Bravura. By all accounts this horn was taken care of extremely well, and is a fantastic player except for one thing: the valves on it get quite slow on the upstroke. The valves look very clean, as well as the casings. I've tried both Al Cass oil and Ultra Pure, cleaning very thorougly between the two. A thorough cleaning does seem to fix the problem for a few hours before it returns. In addition, oiling the valves does fix the problem for about 5-10 minutes, but then they need oiled again.
Since noticing the problem, I've taken special care to watch my finger position to ensure I am going straight up and down on the valves, and that seems to have little effect on the stickiness in playing situations. Though if I just quickly thump the valve down over and over while the horn's in my lap, I can't seem to duplicate the problem. If I apply pressure just slightly left or right, it sticks. It's almost as if the horn is WAY more sensitive to my finger position than any of my other horns, including a Bach, Holton, Committee, and Yamaha flugel.
I've got a good repairman that I'm going to have take a look at it in a few weeks when I get back to town, but in the meantime, does anyone have any ideas?
Any help will be apprecited.
I didn't find the right solution from the Internet.
