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:
