[Phono-L] Edison Diamond Disc size

2011-03-20 Thread Bruce Mercer 
Many years ago I asked Walter Welch what the conical tip size was for the 
DD. He informed me ot was .0075. I wrote it down inside the back cover of my 
then new copy of  Tinfoil to Stereo.

I think I erred in my previous post about the stylus.  The tip is 0.0035
radius  The of .0075 is for the shaft of the stylus.
