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.

Ian Schneller brings 30+ years of experience repairing, designing and building tube amplifiers to this course offering students the rare opportunity to learn tube amp repair fundamentals from a master amp builder in his service shop.

Students who have a grasp of these fundamentals may wish to complete their training in our Tube Amp Repair, Modifications and Diagnostics 2 Advanced course.

Tube Amp Repair I and II is for those who wish to register for both courses, and is offered at significant savings!
