 We have had many requests for an advanced or modification class related to the amp class amps so here it is. This class is geared towards previous amp class builders or at least have some knowledge and/or experience working on tube amps. Not really for the novice/beginner.  Not that you would not learn a bunch of cool stuff but it will be assumed you have some hands on amp experience. Below are a few of the subjects we will discuss in detail. Of course, we are flexible and open to your suggestions and, as always, questions are welcome during the class. There is so much I want to teach you in the two days. This is NOT a building class. You should not bring your own amps as we will not be set up to perform individual modifications or repairs. We can certainly discuss options on any amps and plan to do so. Class will be from 9AM to 5PM both days. Total cost is $300. We will supply breakfast junk and a good lunch both days. You will be responsible for your own travel and lodging expenses.
