The DVD has more video than advertised. Just when we were done watching one we found another set of videos not mentioned and now find a complete and thorough guide with walk thru How to`s. I would buy again if this were somehow lost. Excellent and for the average Joe.

4/5 VISUALLY learn about tube guitar amps
  by Paul D. Van Gorden (Kansas City, MO USA)
As a visual learner, and cautious person in general, I've been hesitant to really get inside an amp to replace components, even after reading all about how to do it on web forums and books.

Combining the 'book' knowledge I've gained, with actually being able to see Gerald at work in this dvd, I have much more confidence in my personal safety and ability to perform basic work on my amps.

This is a logically indexed and fascinating collection of Gerald's videos that completely takes the mystery out of questions like "How EXACTLY do I measure voltage on a live amp?" and "How EXACTLY does one safely discharge a filter capacitor?" for a beginner like me. There are also advanced topics for those that can perform the basics half-drunk with their eyes closed.

Gerald is a controversial figure in the guitar and amp world of big egos and names, and "who knows the most tube theory", but I appreciate the knowledge of old Fender and Marshalls that he shares in this dvd. Worth the price of admission to me.

5/5 Great for anyone looking to repair an amp
