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

AFAIK, Stanton does not supply new styli for the 6000 series cart.  I'd have
gotten a 6027 if I could but as it turned out I got it retipped with a nice
3 mil diamond which works better anyway.

You can always find a local source for something that the manufacturer 
does not recommend.  The entire pull out assembly is supposed to be 
replaced as the suspension is in there and every elastomer has a service 
life.
