Money is not everything. I am surprised for the audio censorship of information and lack of interest by good diagrams electronic amplifiers that are as unique and good. I gave another similar scheme.

For a clean amplifier power transistors must be exactly as reinforcement in the diagram, the load output of the amplifier must be accurate, the type of transistor BC313/211 French or Polish product, Parameters for BC313/211 - Ic = (Ico = 4.5mA + Id = 20mAp) = 24.5 --- 27mA max, parameters for 2SC3182 - Ic = 2Ap/Ro = 4R / b = 240 min.

Higher power amplifier can be done only purely for low output resistance.

Could you help by itemise/highlighting the differences in the attachments of posts1, 2 & 4?

Each of these amplifiers is clean and techniques are similar, small differences between them relate to the power and the output resistance of the amplifier.
