The concenous was that the 13C for a 5mm bb should be less than 10us...
Anyways word travels fast - back to MR - and they have indeed located the
problem with the amplifier and probe (which I am not sure), now giving a
7.75us 90 for the 13C.......
Good things come to those that ask the questions!

PS I must apologize for using MR's name in the original note - I did not
intend for it to be a statement about third party instrumental suppliers.
