@jsd52756 “Not quite lathe chips, but that turntable (Garrard Zero 100) was deplorable”
My scalpel joking aside, l know the Garrard Zero 100 very well. I did only know of one owner who loved it, a girl. I think she just liked the “bling l👀k” with all that see through plastic arm pivot mechanism.
The idea was sound mathematics but the resulting sound was never great. Too much horizontal friction in the engineering to make the null point “zero” all through the record. The cartridge angle movement while playing was a novelty selling point.
As l say, on paper correct tracking was a good idea but there was just too much to overcome with the engineering. Also you could not use the lightest tracking cartridges with so much leveraging to move the cartridge.
In the 70s 1.25 grams was the preferred tracking weight for Shure V15’s and the Goldring G900 series for examples. With the Zero 100 not a good idea… think of doubling that with over 2 and up to 3 grams to stay in the groove. It could never track any of the so called Shure “trackability” test records.
Garrard tried and failed, but they did sell a lot. For the serious hi-fi enthusiast it was only ever considered a gimmick at best.
