I'm learning about transistor configurations (particularly in relation to audio circuits) and am having difficulty analysing this fairly straightforward common emitter stage from the Instrument input of a Roland RE-201 Space Echo. Specifically, I am confused how to find the DC bias voltages for this circuit. If R3 220k was connected to Vcc this would be a standard 4 resistor setup but with it being tied to the collector (which is connected to Vcc through R8 27k) I am having trouble calculating the voltages. Every explanation I have looked at so far brings in the transistor beta at some point in the calculations but am wondering if it is possible without using this (or even without estimating beta) with the known resistors and Vcc of 17v.
I tried looking at it in terms of a voltage divider but don't end up with the 5v Vc that the schematic shows:
Vb = 17 * ( 47k / [47k + 220k + 27k] ) = 2.71v
Ve = Vb - 0.65v = 2.06v
Ie = 2.06 / 560R = 3.6mA
Ic = Ie
Vc = Vcc - (27k * 3.6mA) = wrong!
I think I'm perhaps incorrect with my first line of calculation as there may possibly also be a resistance to ground from the collector through the transistor (?) which I imagine should be considered, but I don't know how to factor this in.
Can anyone offer some advice?
Many thanks in advance
EDIT: schematic re-uploaded to show that C6 / R10 are connected to other audio inputs which go through a separate amp stage and so bypass Q11.
