Tube amp diagnostics and repair is equal parts science and art – there are very few places to learn it and few masters of the craft willing to divulge their hard won secrets. Students will learn the fundamentals of tube amp electronics, diagnostics and repair from the standpoint of the electronics repair professional. This course is the perfect choice for the beginner.

No prior electronics experience necessary.

Students who complete this course or who already have a grasp of these fundamentals may continue their training in Tube Amp Diagnostics and Repair II course.

Tube Amp Repair I and II courses are offered in series at significant savings.

His extraordinary amp diagnostics curriculum is well thought out and comprehensive. Here is your chance to learn from a master amp technician who is one of the best in the business.
