A FesZ Electronics video credited with showing how wire wound on a ferrite core can serve as a workable homemade AC current probe.
FesZ Electronics explains the capacitance multiplier using LTspice simulations, cited as a clear account of how a cheap circuit cuts supply ripple and noise.
A favoured LTspice tutorial series that several people return to as their regular reference and suggest as a starting point for simulation.
Fesz video cited for transistor amplifier theory, including how an RF choke at the collector lets the voltage swing above the supply in class A designs.
