Tube Amp Diagnostics & Repair I

Diagnostics and repair of a tube amp is perhaps 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.  This seminar offers a rare opportunity to learn the fundamentals of the art and craft of tube amp diagnostics and repair with master amp technician Kye Kennedy. This class represents more than just the keys to a vocational opportunity – here’s a chance to learn from one of the best in the business._DSC3107
