It meets the road and gets moving fast, with 12 tube filled chapters of information, lots of good material to ponder.This volume is sub-titled ‘How To Repair, Modify & Build Guitar Amps’, and it definitely covers all this ground and so much more. The first chapter jumps right in and carries the heading: ‘Output and Interstage Transformers for Tube Guitar Amps’. Quite a mouthful in itself, and quite an array of output related topics:Output TransformersInterstage TransformersDesign Example: 5kΩ Push-Pull Output for Guitar AmpsAnalysis: Ordinary and Simul-Class Mesa Output TransformersTesting Audio TransformersLine-Matching Audio Transformers’ in Push-Pull Output ServiceDual Primary Power Transformers as Output TransformersThat’s enough of that.Other chapters include: Loudspeakers, Troubleshooting and Repairing, Wiring & Soldering, Power Supply Mods, Tone Tweaks, Push-Pull Amps, DIY Projects, Rebuilding Amps in Hardwired Fashion, DIY: Quirky & Unusual, Converting Vintage Tube Gear Into Guitar Amps.The first two chapters deal with final stages of amplification. Chapter three jumps into troubleshooting. Practical wiring, and soldering are covered in chapter four. Power supplies and tone changes are part of chapters five and six. Chapter seven reviews and analyzes some modern push-pull amps.The final four chapters are full of actual ‘hands on’ material that you may wish to attempt. Or, at the very least, learn about. The author takes the time to carefully number the areas of his photographs that are being discussed. The black and white photographs are clear and useful additions to his explanation, and those numbered additions aid the reader in locating the points of interest.I want to comment on the overall graphics in this book. The schematic diagrams, usually containing vacuum tube components, are clear, but more importantly they are rather handsome looking graphics. They are nicely presented. I just had to say that being the artist that I am.I got excited when on page 200 the author dives into a Heathkit A7-C amplifier from 1955! I just get excited about all things Heathkit.Later in the book the author investigates using some vintage EICO equipment for converting into amplifiers for guitar use. Signal Tracers, and Audio Generators are discussed and conversion options presented. A way of saving money for ‘novice’ amplifier engineers of the future, or all you DIY folks out there.The last five chapters will take the reader through at least a dozen unique amplifier designs that use quite an assortment of pre-amp and output tubes. Some commonly known tubes, and others less common are discussed. Something for everybody.I have not listed the names of the guitar amplifiers specifically discussed in the various chapters. All the names are new to me, not being a guitar amplifier person. However, I can’t say that I haven’t been exposed to those names now. I can easily see inside each of them by looking through this volume two book, I’m somebody now.So what I was looking for in Volume One of this series, I found here in volume two. That is why I titled this review as I did. If you want to seriously get inside some guitar amplifiers, this book will not disappoint you. It may, however, overwhelm you. Not sure.I now have a third book by Mr. Popovich staring me in the face as I type this. I am also looking forward to that tome titled, ‘How To Use, Calibrate, Repair And Upgrade Vacuum Tube Testers’. I guess I’m just a glutton for punishment when it comes to technical books.I see where the author has a series of books for audiophiles. I’ll guess that they are all equally as informative as his guitar amplifier books have been. I will not be buying those volumes myself. Someone else will have to review those beauties.Now, who should purchase this book? If you’ve read this far into my review, I’m guessing you’re seriously considering this purchase. Just buy it, you won’t regret it. You can use it as a resource throughout your adventures inside guitar amplifiers. It won’t be too many years from now when this area of expertise is lost to time. Then these books will become sought after treasures to possess. I’m very serious here.Who knows, eventually 3D printers will produce plastic versions of vacuum tubes, with carbon impregnated pins (if they even have pins), conductive films coating plastic grids and plates. I’m not sure how the plastic will take to heater filaments, but where there’s a will there’s a way. Of course, 3D printing doesn’t have to be limited to only plastic models now does it?Thank you Mr. Popovich for all your hard work. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great source for learning amp builds *by J***Y on Reviewed in the United States on July 7, 2022* This book was an excellent source to start on my way to building guitar amplifiers. There is much information and a lot of different designs to study and learn from. Great information and very well written. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Item as described. Satisfactory/Adequate.
