Abstract
All electronic circuits require a power supply of some sort. Many times the power supply for a circuit will simply consist of a 9 V battery, which is especially true for guitar effects boxes and pedals. In this chapter we will examine the operation of linear single-polarity, and bipolar power supplies, as well as basic vacuum tube diode based power supply circuits.

Technically, the space charge region occupies the entire space between the cathode and the anode, but unless a forward bias is applied to the tube, virtually all of the electrons remain very close to the cathode surface.
