This clavichord was restored by Felix Wolff in 1971. String thicknesses and string materials used for the calculation of the string tensions are those chosen at the restoration.
The tangents have been replaced several times, so the original positions are not known. Probably the original intention was a quarter-comma meantone tuning. In that case the lowest frets need tangents positioned close to the edges of the outer keys and leaning a little outwards.
For a discussion of this choice see Clavichord International Vol.10 No.1 May 2006, pp. 17-20: HansErik Svensson, Comments on the tuning of some fretted clavichords in the Stockholm Music Museum.
In a later restoration the tangents have been positioned in the middle of the keys. This means that the present tuning had to be a compromise.
