Tube Amplifier Building Workshop
This workshop consists of five 3-hour sessions. The April weekly session is now full. We will open another weekly session soon.
If you would like to receive an email from us when registration for another weekly session is open, sign up below for our newsletter.
- The kits are supplied by Mojo Music. The parts included are excellent quality and the cabinets are pre-assembled and beautifully covered in authentic tweed fabric. Every aspect of the kits is as faithful to the original design as possible. Each kit comes with its own schematic and layout diagram (there are no assembly instructions included). Click here for more information about the kits.
- This workshop will be divided into part lecture,
part demonstration, and part hands-on training.
Over the duration of the five classes, students
will observe stages of the kit building process
and then carry out the work on their own amps
under the supervision of the instructor. Enrollment
will be limited to 8 students per workshop.
While this is not a design class per say, students will obtain a foundation level understanding of the way a vintage tube instrument amplifier functions, stage by stage. Students will also learn the craft of point-to-point wiring and how to modify a circuit to shape its tone by changing component values. Moreover, by building an amplifier, students will begin to develop the diagnostic skills necessary to troubleshoot and repair other amplifiers.
The legendary circuits used in this workshop are the same ones that have made true “Tweed” era amplifiers so revered among musicians. These amps are bullet-proof workhorses that are easily serviced, modified, and maintained. Through this workshop, students will discover the beauty of cloth-covered wire, heavy transformers, chassis-mounted components, and finger-joined pine carcasses.
- Build an amp that both you and your great grand-children can enjoy!
- Workshop Materials and Supplies
- The school will provide each student with their own individual workstation and have tools available for use. Students can select which kit they will be building from the list below.

- A Note about Amp Kit Selection: It is strongly recommended that the beginning student build either a Champ or Deluxe as these circuits have fewer connections and are more straight-forward. For students who have a bit more experience wiring and soldering, or who are willing to spend extra time working at home, the higher-powered models are appropriate (e.g., Bassman, 50-watt Twin, 100-watt Twin).
- Tool Kit
- Students may also purchase a personal set of tools selected by the instructor. The purchase of these tools is recommended if extra-curricular work is desired during the workshop or for continued studies. Click here to learn more about the tools and how to purchase them.
