Pickering 2400Q (c. 1973)
Not much is documented about the Pickering 2400Q. What survives comes from period magazine mentions, not manufacturer literature. The early 1970s press called it by its fuller name, the UV-15/2400Q. High Fidelity (October 1973, p.66) listed it in its roundup of CD-4 playback equipment, noting the Quadrahedral stylus and a U.S. price of $125. HiFI-Stereo (October 1973, p.76) grouped the same cartridge with Shibata-stylus CD-4 designs and confirmed the $125 price.
That is about all the record holds. The sources available to the Archive don't give production years, full technical specifications, or packaging details. The period press confirms only the following.
- Phono cartridge for the CD-4 Quadradisc format
- Quadrahedral stylus (Pickering's CD-4 stylus design)
- $125 in 1973 period reviews
