FET 10/PC

About the FET 10/PC

The Threshold FET 10/PC is a dedicated standalone phono preamplifier/RIAA equalizer for MM and MC cartridges, designed by Nelson Pass in the mid-1980s. It offers selectable gain of 40dB (MM) or 60dB (MC) at 1kHz, switchable cartridge loading, and an external power supply. The unit's published loading options include 22, 47, 100, and 1,000 ohms for moving-coil cartridges, plus 47k ohms for moving-magnet cartridges, with capacitance options of 50, 100, 150, 250, and 1,000pF. Published specifications also list a frequency response of 1.5Hz to 150kHz, RIAA accuracy of 0.025%, THD of 0.01% at 1V output, output impedance of 110 ohms unbalanced and 220 ohms balanced, and dimensions of 19 in W x 2 in H x 10 in D.
