Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having ...

If we had to pick one part to crown as the universal component in the world of analogue electronics, it would have to be the operational amplifier. The humble op-amp can be configured into so many ...

Part 5 provides spec summary of the GP/R K2-W vacuum-tube op amp and discusses measurement constraints/conditions and LTspice modeled output. The K2-W vacuum-tube op ...
