I’m kind of self-trained in EE. It is important to have basic courses in Signals & Systems and logic design. The former, in particular, is not something that you are likely to acquire on your own. You and I share a love for Purcell. However it has little to do with EE. It is a physics book, and EE is not physics. You will never use or need to even know that the magnetic field arises from a relativistic transformation of the linear charge density of a current. I have a recommendation. Become an expert in LTSpice. Also, for about $2k, you can assemble a nice lab of Chinese scope, power supply, multimeter, soldering station, selection of ICs, resistors, caps, and a power supply. And if you are going digital, you need to learn VHDL.
