Designing Power Supplies for Tube Amplifiers by Merlin Blencowe

Tube amplifiers are electronic devices that use vacuum tubes to amplify audio signals. They are popular among audiophiles and musicians for their warm and natural sound quality, as well as their ability to produce rich harmonics and distortion. However, tube amplifiers also require a reliable and stable power supply to operate properly and safely. A power supply is the part of an amplifier that converts the mains voltage into the voltages needed by the tubes and other components. A poorly designed or malfunctioning power supply can cause noise, hum, instability, overheating, or even damage to the amplifier.

Designing Power Supplies for Tube Amplifiers is a book by Merlin Blencowe, an electrical engineer and tube enthusiast from the UK. The book is a comprehensive guide to the design and construction of power supplies for tube amplifiers, covering both theory and practice. The book explains the principles of power supply design, such as rectification, filtering, regulation, protection, and grounding. It also provides detailed examples of various types of power supplies, such as tube rectifiers, solid-state rectifiers, choke-input filters, capacitor-input filters, shunt regulators, series regulators, and more. The book also includes tips and tricks on how to troubleshoot and test power supplies, as well as how to optimize them for performance and efficiency.
