Folks,
I haave read with interest all this stuff about the effectiveness of the Bearing Base Plate, and now in recent posts, the Bearing.
Some of you may rcall that I had a discussion on this forum with a fellow who had a recording stuio and obviously new a little about what he was talking about. I have forgotten his name.
I put forward the idea that if a SL1200 were fitted with a second arm and a record was produced with blank tracks in between the sound
then the second arm could be used to detect any backgroung vibrations ie noise generated by the sound track.
This approach would not be exclusive to detecting quantative bearing or base micro vibrations as there would also be energy conducted along the surface of the record. However it would serve as a comparitive measurement for those who are so aching for measured data to help them hear the music.
Maybe someone would like to follow up this idea.
