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.

Audio Designs With Opamps
https://sound-au.com/dwopa.htm
The operational amplifier was first used in the 1930's as the basis of analogue computers, and much development took place to design accurate gun aiming systems during the Second World War. Since integrated circuits were unknown at the time (this was before the invention of the transistor), the earliest versions were made using valves.

LM358 op-amp, which is a low-power device that can be operated from a single voltage supply, therefore appropriate for battery-operated circuits. Low-power op-amps draw very little quiescent current and hence help prolong the life of the battery. The LM358 is a

sizes material required for speedy op amp design. The ideal op amp equations are devel-oped in Chapter 3, and this chapter enables the reader to rapidly compute op amp transfer equations including ac response. The emphasis on single power supply systems forces the designer to bias circuits when the inputs are referenced to ground, and Chapter 4
Operational Amplifiers: Basics and Design Aspects
https://www.mcvts.net/cms/lib07/NJ01911694/Centricity/Domain/134/Op-Amp%20Basics.pdf
The circuitry that makes up an op-amp consists of transistors, resistors, diodes, and a couple capacitors. In general, these components are combined to achieve within the op-amp two stages of differential amplifiers and a common-collector amplifier. [1] In an effort to simplify the operational amplifier, one must not forget that the

We will use an Operational Amplifier and two additional power transistors to deliver the 10 Watt output across the output load Construction Topology for Amplifiers. In an amplifier chain system, the power amplifier is used at the last or final stage before the load. Generally, the Sound Amplifier system uses below topology shown in the block diagram
