I have constructed a discrete audio amplifier with a Class A input stage and a Class AB emitter follower output stage. I have not been supplied with the AC value of Vin. Does anyone know how to determine this value? I must calculate the ac values of vb, ve, and vc.
Thanks
The base resistance of Q2 must be adjusted to produce a quiescent voltage of +5 volts at the emitter of Q3.
adjust the input voltage to yield an ac load voltage (Vout) of 4 Vpp
adjust base resistance (R7) of Q2 to product a DC voltage of +5 volts at the emitter of Q3.
I have added a new schematic with 0 volts input
