Is it possible to build an OpAmp without using an integrated circuit or a transistor or a vacuum tube? I wanted to see how it would look on a larger scale before miniaturization on a chip.
I was hoping for a high view of what that would entail, not only that it is logically possible.
@HarrySvensson Thanks. That is what I wanted. I didn't mean to cause a ruckus. I only wanted to see what was going on outside of all the YouTube videos and all the rest. I figured if I could see it with big chunky non-IC parts, I could understand it. Apparently I miscalculated there.
What I should have asked for was an equivalent circuit. Now I know the keywords to search and have found many.
