A lower Tl solubility limit of (2 –y)= 1.25 was found for all n, but the upper limit decreased from 1.89 for n= 1 to 1.80 for n= 2 and 1.65 for n= 3. Under our controlled synthetic conditions, which allowed variation of the Tl concentration under similar temperatures and oxygen ...
A metal spacer plate (7) is arranged between the neck (5) and the body (4). For fretted instruments (9,10), a magnetic coil (14) with broad band characteristics is arranged on the body (4). For fretless instruments (11,12), the magnetic coil (14) has low-pass characteristics. ...
