The Four Power Supplies

Four Different Types of Power Supply, Part 1: RMS, Diodes, Half-Wave Rectification
Uncle Doug - Published on May 5, 2016
This is the first video in a series that will explain the function and differences between four different types of power supply: 1.) The Half-Wave (commonly used for tube bias negative DC voltage) 2.) The Full-Wave (most common of all tube amp power supplies 3.) The Full-Wave Bridge (very efficient, it utilizes a less-expensive power transformer than FW) 4.) The Voltage Doubler…..and how it can be used to build very economic tube effects, like a boost and tremolo unit, or even a simple low power amplifier. For many of you, this will be your first experience with this very interesting and useful circuit.
