Anyone have some technical info on this. Trying to locate a schematic. Company is still around but minimum repair and calinration is $1,000. Even if you just use one, that would help. Thanks
I should post this on another thread. Anyone familiar with high end audio knows this as the gold standard for many years to perform IM and hamonic distortion measurements. Although form follows function, there are some fine points in the procedure I would like to learn.
