I have a 1958 Paris Selmer large bore and use Blue Juice. IT IS FAST AND LONG LASTING.

I had problems with a mushy upstroke on one of my Getzens. Running the valves through an ultrasonic jewelry cleaner with a 2-1 mix of warm water and white vinegar solved the sticking problem.
Installing new valve springs also helped.

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.
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? |
The first thing I'd suggest is to tear it completely down and give it a good thorough cleaning. A chemical bath is the best way to do this, but if you don't have access to that until you take it to your repair guy, soak it in the tub to help loosen everything up and then clean each part very carefully with the proper brushes (you can buy a cleaning kit at most music stores or online) and flush thoroughly. That will help remove any goop, gunk or whatever nastiness may be lurking in the valves and tubes that could be causing it to hang up. Then use a good quality oil to lubricate the valves (i.e., the pistons) it when you reassemble it.
If it still occurs, then it could be something like the valve casing is out of round, the valve itself is slightly bent, etc. A good repair tech can easily fix those issues though, to get it playing like it should.

It's been a month shy of 14 years since the OP laid this problem before us. If it isn't solved by now, well . . .
