Grado GF-1

The record on the Grado GF-1 is about as thin as it gets. The fact file for this model came back empty - no production years, no confirmed specifications, no family placement. The only period material is two cartridge-directory scans, and both are damaged enough that the GF-1's own entry can't be read.

The earlier scan, from HI-Fi-Stereo-Buyers (1984, p.72), is a Cartridges & Tonearms roundup. It carries Grado entries with elliptical diamond styli, 5 mV output, 10-35,000 Hz response, and 20 dB average separation. The OCR garbles the model names, so none of those figures can be traced to the GF-1 specifically. The later one, Audio (October 1996, p.150), is that magazine's annual phono-cartridge directory. Its stylus-type legend is legible, but the GF-1's line entry isn't.

Those two scans bracket the era in which the GF-1 was likely in Grado's lineup, and they place the model among the phono cartridges the archive's audio section covers. Beyond that, it is under-documented. If you own a GF-1, or have a clear photo of its packaging, the archive would like to see it.
