That is a pretty extreme fix....fortunately my KSL is quiet. Phono starts to get noisy above 2 oclock increasing to full tilt with no music playing. I listen between 10 and 1 now that the phono board is fixed. They may exist but I haven't owned a phono stage that was dead quiet when turned that high.
