Hi, folks!
Could you please help me understand this soviet-time 12V power supply circuit?
As I understand, it is a constant 12V power supply with adjustable current control via the R120 variable resistor. The DA2 is a dual-supply op-amp similar to the 741.
What I do not understand is how the NMOS transistor VT25 works in this circuit as well as the transistor pair VT26 and VT27.
Could you please help me understand how this design works?
Thank you for your help!
