| Marc - the valve caps and valves are on tight so I don't think it is that. M and C - I have Zaja Blue which I am using on my Yamaha trumpet - it works well on that but was really bad on my Besson Cornet where Al Cass is much better. I could put Zaja Blue on my Schilke but I read somewhere, dodn't know if its true, that Schilke designed the valves with Al Cass in mind. Also this is a very loud metal clicking noise that is really only on one valve and not the others so I am not sureif it is a choice of valve oil problem. I will try thye Zaja Blue on my Schilke though to check. Thank you both for your thoughts,
Graham. |
