[Vintage-Audio] Re Cartridges and Styluses

Mon Jun 30 14:20:01 2003

Pete, 	

Some were 1 mil and others were 3 mils in depth. The older vinyl required
anywhere from 3-6 grams, remember putting a penny on the tone arm? That penny
weighed 4.11 grams! 	

There was a change in the depth and width of the grooves somewhere back there
and the stylus and tracking weight changed also. I believe it was the late
sixties to early seventies, but I would not swear to it. I do know that there
were several variations in the fifties. 	

Yep, I remember those flip over stylus/cartridge units. Did they ever come for a
turntable though, or just a record changer?

I thought the tracking weight had to do with the type of stylus and/or
cartridge and the type of tone arm and its balancing mechanisms. I seem
to recall  playing 78's required a different stylus size than for 33 or
45 records but not a different weight. Many of the ceramic cartridges had
the typical turnover mechanisms (1 side of the cartridge for playing 78's
and the other side for 33 and 45 playing; each side with a different
stylus size) mounted in the arm head. Many magnetic cartridges required
changing out the plug in stylus. I don't recall ever considering the type
of vinyl when using the various measuring tools to set up the initial
parameters on a tone arm.
