You might want to try loading it up with al cass or even a good chemical clean. I once owned a 176 merker that was a terrible horn and came new from the factory with some not so lightning fast valves- the second valve seized up after about a good month of regular playing. I sent it to my repairman and he said the valves were corroded from sitting in the back of a music store- a good chemical clean and I was ready to trade it off for something decent- an elkhart 8d!
There's my two cents.......plus a quarter for owning a holton for a length of time...lol hoss The tired (no really it's really late here) _______________________________________________ post: [EMAIL PROTECTED] set your options at http://music.memphis.edu/mailman/options/horn/archive%40jab.org
