Gerald Weber’s 20-Lesson Tube Guitar Amp Electronics Correspondence Course Training.

Want to learn everything you need to know about the basic fundamentals and basic electronic principles going on in a vacuum tube Guitar amp?

My 20 Lesson Correspondence Course is the fast track to learning Vacuum Tube Guitar amp basics. It will lead you from knowing nothing, to knowing everything you need to know about Vacuum Tube Guitar Amplifiers!

It is written for people with little or no electronics training and will take you step by step through all the basics. It is presented in logical order with each Lesson building a foundation to the next, so that you will have firm footing of everything you need to know. You get one on one, interactive training.

Here is how it works. We email you Lesson 1. You read the material and email the homework back. I grade the homework and return by email any needed corrections along with Lesson 2. We continue in a like manner, at your own pace, until we complete all 20 Lessons. At the end of the course, you will receive a Certificate of Completion. Here are the topics covered:

Here are what the alumni have to say about it!

"This course was amazing! The way you broke down every section and the flow of one lesson going into the next lesson was great. There is a lot to learn in this course from beginners to advanced. I would recommend this course to others because of the way it is set up. It is just perfect for beginners who don't know a thing about tube amps."

Dell Aquila

"I am impressed with the course and the foundational knowledge that I have gained. It has been money well spent. I have recently retired and was looking for a way to stay busy and make some extra money using both my hands and mind while working at home. This course has given me the confidence that I have the knowledge to repair and overhaul tube amps and I am looking forward to the future. Thank you Gerald and the others that have put this together. I would most definitely recommend this course to anyone who was interested in the inner workings of tube amplifiers. The course takes you from knowing nothing to gradually feeling confident that you could start working as a tube amp tech."

David Nodes - Whiting New Jersey

"This course has been very fulfilling for me. I have gained a great deal of knowledge and I have enjoyed each lesson. The lessons are very clear and focused. Each lesson covers a subject area and builds into the next lesson. I have had a great experience and am sad to reach the end. I would recommend this program to anyone interested in tube amplifiers or any other tube based technology and/or theory. The course contains both a great deal of theory and practical common sense, good advice and alternative methods. If you are willing to put in the effort this course is very fulfilling."
