Type A: for harpsichords, virginals and clavichords with a scaling of up to 37cm (14.5") for c" at a pitch of a' = 415Hz, and up to 35cm (13.75") at a pitch of a' = 440Hz.  Recommended maximum practical tensions are:

0.19mm                     3.1kg                                       0.27                           5.5

0.21                           3.7                                           0.30                           6.4
