...but aren't all of the PT-line of F tubas 19-21mm bore??
Not to question your post - I'm just wondering:
In my B&S catalogue there is no PT-9 listed (for some reason) but there is a model 3100 which has 6 valves (4+2) and the bore is 17-21mm like the older pre-perantucci line. Is this the PT-9 then or does that have the 19-21mm bore? The PT-12 is a 6-valve version of the PT-10 as 4+2. Could the PT-9 be the 5+1 version of this?
If it's not the same, could that make much difference? I presume it could...
