Plus, since they are such heavy and bulky components, international postage or courier costs are significant.\u003c\/p\u003e\u003cp\u003eThe physical principles behind transformer operation are quite complex and mathematical modeling of transformers require strong mathematical skills, deterring amateurs and DIY enthusiasts from studying the subject. While some basic understanding of operational principles is necessary, luckily, transformer design can be greatly simplified by using a few basic rules-of-thumb formulas.\u003c\/p\u003e\u003cp\u003eLikewise, once you have a finished design (a detailed winding diagram), transformer winding \u0026amp; assembly is surprisingly easy. Apart from the materials (such as bobbins, laminations, insulation and magnet wire), all you need is a simple winding machine (can be of DIY variety), good hand-eye coordination and patience.\u003c\/p\u003e\u003cp\u003eYour DIY transformers will almost always be significantly cheaper than commercial alternatives and often of better quality and better sounding than famous names transformers costing many hundreds and even thousands of dollars each.\u003c\/p\u003e\u003cp\u003eThere are more than 40 (!) detailed designs of various power, output \u0026amp; interstage transformers and filtering, grid \u0026amp; anode chokes in this unique manual. Even if you don't feel like investing time and effort into mastering the art of transformer making, simply take those winding diagrams to any transformer making shop and have your transformers professionally made for a fraction of the price of commercial alternatives.\u003c\/p\u003e\u003cp\u003eThis practical design \u0026amp; construction manual is richly and professionally illustrated with photographs of transformers, circuit diagrams, winding diagrams, reference tables, graphs and charts. These valuable illustrations make it faster and easier to comprehend issues and concepts. A picture is truly worth a thousand words. Indeed, all the information required to design, wind and test chokes, power and audio transformers is within these covers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCONTENTS: \u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003ePHYSICAL FUNDAMENTALS OF MAGNETIC CIRCUITS AND TRANSFORMERS \u003c\/li\u003e \u003cli\u003eFILTERING CHOKES (INDUCTORS)\u003c\/li\u003e \u003cli\u003eTRANSFORMER MATERIALS, CONSTRUCTION METHODS AND ISSUES\u003c\/li\u003e \u003cli\u003eMAINS (POWER) TRANSFORMERS\u003c\/li\u003e \u003cli\u003ePHYSICAL FUNDAMENTALS OF AUDIO TRANSFORMERS\u003c\/li\u003e \u003cli\u003eSINGLE-ENDED OUTPUT TRANSFORMERS\u003c\/li\u003e \u003cli\u003ePUSH-PULL OUTPUT TRANSFORMERS\u003c\/li\u003e \u003cli\u003eSPECIAL MAGNETIC COMPONENTS: LOW POWER INPUT, PREAMP OUTPUT \u0026amp; INTERSTAGE TRANSFORMERS, GRID \u0026amp; ANODE CHOKES\u003c\/li\u003e \u003cli\u003eOUTPUT AND INTERSTAGE TRANSFORMERS FOR TUBE GUITAR AMPS\u003c\/li\u003e \u003cli\u003eTRANSFORMER TESTS \u0026amp; MEASUREMENTS\u003c\/li\u003e \u003c\/ul\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Igor S.
