Gate Emission Regulator
Zychlix/ECR
This is an emiter cathode current regulator. It works via affecting gate potential in reference to grounded anode

The TL074ACNSR is a FET Input Amplifier made by Texas Instruments in a SOP-14-208mil package with 14 pins. -20V~20V 0℃~+70℃ 1.4mA 100dB 10V~30V 18nV/√Hz@1kHz 18uV/℃ 20V/us 3MHz 3mV 4 5pA 65pA Short-Circuit Protection、EMI filtering/RF suppression SOP-14-208mil FET Input Amplifiers ROHS.
PCBKit's library has its KiCad symbol (Amplifier_Operational:TL074, from KiCad's library) and its footprint (LibrePCB_Base:DIP762W55P254L1905H533Q14_hand_soldering, from Librepcb), ready for a KiCad board. JLCPCB lists it (part C2059184). 1 open-source board in 1 repository on GitHub use it.
