Hello gang:
Designing a common source (Vdd 12VDC) amplifier to drive a tube input stage. I need to select a JFET (or mosfet?) that has very low noise. Data sheets don't really show NF's. I am looking at a J (174 or whatever) series or maybe a 2N3819, but I am open to other ideas aside from op amps or BJT's. Any suggestions?
