These are some original Garrard Standard Magnetic Pickups I have.
“…is of robust design and has a good frequency responsewith a voltage output sufficient to load any average amplifier” they stated on their literature at the time.
Plug-in type made of bakelite and used the standard gramophone needle with a screw at the front to facilitate the replacement of needles.
Output 0.5V at 1Khz
Needle Pressure on record was annouced as over 55g… (2 oz)
Impedance 9KΩ at 1Khz
Coil resistance 2KΩ
