Outlines, in schematic form, many approaches that achieve the goal of power scaling, super scaling and power management. A complete history and discourse on the technology outlines how to implement multiple power scale controls, alternative circuit forms and system impacts. Further tutorials outline the methods for super scaling, with both fixed and variable boost ratios, using both solid-state and tube methods.

Power management is explored, covering

• AC and DC current limiting
• voltage restoration
• voltage clamping
• sag control systems both active and passive
• R-M-X and G-M-X techniques
• composite zener circuit applications - the latest trend in tube amp biasing
