I too learned a lot from Spice. But I was familiar with linear systems, circuit theory, op amps, and had a decent lab with components, a soldering iron, a scope, a signal generator, and a meter. For me, you have to build stuff to really understand. Imagine my surprise when I discovered that a simple 7805 regulator’s output voltage wasn’t 5 V with no load!
