OK, so I changed R2 in my schematic to 11K4:
I now see the voltage over R2 drop slightly to 1.35V from 1.4V with smaller values of R2. (3K3 or so)
Also the voltage over R1 drops slightly to 1.92V from 2V after the change of R2.
The current through R2 is now 0.12 mA and close to where I want it. (Assuming a Fairchild 2N5087, correct datasheet
and valid info for this circuit; i.e.: info in Rsource versus Icollector graphs is relevant for an emitter source follower)
(9.34V from + to GND, 0.56V over base-emitter, 7.41V over base to ground)
If I build a stereo version of this circuit, how much is the leakage of audio over the resistors?
The battery is low impedance but need I take extra measures to prevent crosstalk?
Assuming that turning the emitter follower into an amplifier/attenuator would introduce too many extra parts or issues (see my previous question) I will do some tests to see how the circuit performs. What is the clipping point for the signal in this transistor setup?
