741 Op Amp tip

I know I have covered this before but when I was searching up something for my power supply build I came across a schematic for a proper supply divider. This schematic came from a book a friend gave me a while back. The circuit was published in 1971. I also tried it out and it works well.


The circuit uses jellybean parts and very cheap to build. The transistors act as current boosters in the feedback loop of the control circuit.
