[Phono-L] Shellac records and damage from steel needles

You can buy a cartridge for your turntable that has 5 to 7 mil conical 
diamonds.  You might find that the standard stereo stylus might miss the 
existing wear and produce a clean reproduction of badly damaged 
originals.   These will fit into any of the modern turntables and play 
mono records.  The Thorens TD 126 Mk III is not a bad choice if you do 
not have one.  It will cover the 78 rpm to 80 rpm speeds without a lot 
of work.  You will be surprised how good some of these old recordings 
sound.  I think Kurt Kauck has information on the details of setting 
this up on his website, complete with pictures.
