So I have calculated with 10 mA-devices
working at about 2-3mA, when doing my calculations
for either single-stage or diffI had the thought about,
JFET+ bipol low-noise, cascoded foldback,
at 2+4 mA as input-stagein a single-end voltage amp
current-source from positive voltage
feeding both that input-stage and a resistor
connected to 0v, as load
determining gain together with the emitter resistorhave to have some solution to how
to feed that emitterthis combined with an output-buffer
of high gain, class ABut of corse if possible Iwould like to buy
dual-devices of
2SK389
I might do some research about retailers.groman
