More food for the mind.... I did not realize Mercury is so dense that a heavy steel platter can float on it.

There is an oil film on the mercury when you look closer to the drawing to prevent evaporation.. Anyway, i would be scared to build something like that. The Michaelson-Morley experiment to measure the speed of light was done by floating a granite plate in mercury. Yes, it is quite heavy.

2 days ago a dream came true. AS brought me a Wandel & Goltermann measurement system from 1975 he had saved for me. It can measure harmonic distortion and intermodulation.
Also level. Specs are not so impressive then say an Audio Precision or Rohde & Schwarz but what i read on the web practical specs are much better then the claimed -80dB. This is from a time where the manufacturers gave minimum specs under worse case conditions.
The building quality is overwhelming. This is heavy, properly made machinery.

I am setting up a comparison and listening test of MC transformers. I have the Sowter model 8055, with and without PCOCC wire, the Lundahl 9226 amorphous cobalt, the Lundahl 1933 nickel and the Silvercore MC100/20 with silver wire from Germany.
