LTspice simulation of the K2-W Vacuum Tube Op Amp’s design reveals the mad science that created a commercial revolution in 1950s and 1960s analog computing. The K2-W's first-stage differencing ...
This way, 10 simulations will be run, each with a different resistance value between 1 KOhm and 10 KOhm. As usual, the different behaviors will be studied with the LTspice and ngSpice software.
