Tube Amp Sag. Chapter 3. Capacitor and Rectifiers Pt 2. Capacitor Short circuit and Inrush current.

In Chapter 3 of our series on Tube Amp Sag we continue our look at the role of capacitors and rectifiers. By the end of this chapter, you have a better understanding of how filter capacitors appear as a short circuit when we power ON or switch from Standby to Play mode.
You will also see capacitor inrush current in action.

This series of chapters on Tube Amp Sag will come out weekly so please subscribe and press the Notification Bell to be alerted as to each new chapter. I hope you enjoy and get something out of the series. Enjoy Chapter 3.
