I have a few weeks with a problem in the design of my bench power supply. First of all I have this design from this guy on YouTube https://youtu.be/_CFIovMkRyg that made a variable power supply using two of four op amp LM324 and the PSU behavior is really stable perhaps I don't find a way to get work that design in LTSpice.
Here's a snapshot of the video showing the design he used.
Here's I've tried so far in LTSpice.
I think is a reference ground problem because he has two grounds. When I simulate all the current from the current source is sinked by a single OPAMP and doesn't matter the value of the pot wiper the control doesn't work. In any case Does this design really work? if it doesn't work, you know a way to make it work?
