I think I can respond to this. I am a Finke rep and I also play a
Brendan triple as my main axe.
It is true that Finke updated the composition used in the valve
rotors to a more stable and less temperature sensitive material. Around
2003-2004, they also upgraded to a much improved ball bearing linkage system
and refined their valve manufacturing process the result of which was/is
that the rotors are centered in the casing with very great accuracy and
consistency and the linkages are quiet and require no maintenance or
adjustment other than regular linkage lubrication (I recommend and use
Hetman # 13, but Finke also sells their own). As far as I am aware, all
Finke horns I've sold and delivered since then have had no problems with
valves. Prior to these improvements, I had to often repair valves before I
could deliver the horn and I had to constantly adjust the linkages for
correct operation.
Sincerely,
Loren

"That's the guy (I hope you chime in!). Does that mean you had an older
(1990's) Finke? Johannes told me that they discovered the hard way that his
old composite would break down under certain conditions, so in the early
2000s, when he found a more stable material, he retrofited any horn that
needed to change (many of them for free). Has anyone had a problem with the
valves on a horn that is less than 10 years old?"
