Almost any type of op-amp capable of delivering 1-5 mA current can be used for this circuit. Most of any small transistors with maximum collector current handling around 100-200 mA can be used. The resistors R1 and R2 should be selected to supply the biasing point at 0.5Vcc, chose as high as possible but keep below 1/10 of op-amp’s input impedance.

The capacitor between the output of the op amp and the amplifier is no more required. The output of the opamp can then be connected across a resistor of 47 to 1000 Ohm against ground to generate the control current for the output stage. The feedback resistor has to be connected always to the amplifier output.
OPERATIONAL AMPLIFIERS: Basic Circuits and Applications

- The Operational Amplifier (op amp) was invented in the 40’s. Bell Labs filed a patent in 1941 and many consider the first practical op amp to be the vacuum tube K2-W invented in 1952 by George Philbrick. - Texas Instruments invented the integrated circuit in 1958 which paved the way for Bob Widlar at Fairchild inventing the uA702 solid state

Operational Amplifier Circuits as Computational Devices So far we have explored the use of op amps to multiply a signal by a constant. For the inverting amplifier the multiplication constant is the gain R2 − R1 and for the non inverting amplifier the multiplication constant is the gain R2 1+ R1. Op amps may also perform other

Audio Designs With Opamps

Opamps, and in particular some of the best available, have extraordinarily good performance, with low distortion and wide frequency response that exceed anything needed in audio circuits. The venerable NE5532 remains one of the best around, and despite its age it's only comparatively recently been bettered by the LM4562/ LME49860/ LME49720 and their ilk.
