Abstract
When looking at Field Effect Transistors (FETs) I only mean JFETs (Junction Field Effect Transistors) because, when talking about low-noise, they are the only workable ones in the audio field. Whereas they are very good for MM cartridge purposes they are – in singleton configuration – a very bad choice for MC amplification. Like the BJTs, with their three leads to the outer world (Gate, Source, Drain), they can be placed in a circuitry in so-called common source CS, common drain CD and common gate CG configurations.

Remember and see the chapter on op-amps: the noise gain is always >1, thus, GT1.red = 0.904 doesn’t change en.T1.
