Description

Our Tube Amp Making Workshop and Amp Repair I course are given in series, and bundled in Amp Camp to offer the student a most comprehensive hands-on making and learning experience.

Student will enjoy bringing home their own hand wired tube amplifier, and the knowledge and confidence to service it. No prior shop or electronics experience is necessary.

Students can choose to make either a guitar amp, or a stereo hi-fi  tube amplifier in the Tube Amp Making Workshop. By constructing an tube amplifier, students will begin to develop the skills necessary to troubleshoot and repair amplifiers. They will follow the Tube Amp Making course with the Tube Amp Repair 1 Fundamentals seminar.

Guitar Tube Amp Making
Students will observe the stages of the building and wiring process and then carry out the work on their own amps under the supervision of the instructor. Students will obtain a foundational understanding of the way a vintage tube instrument amplifier functions, stage by stage, and learn the craft of point-to-point wiring and how to modify a circuit to shape its tone by changing component values.

Hi-Fi Stereo Tube Amplifier Making
This Stereo Hi-Fi circuit is wired point-to-point but differs from the circuits featured in instrument tube amp making in that it uses individual turrets wherever necessary. The amp circuit constructed in this workshop is derived from the classic single-ended designs that began in the 1930s.  The design is organic and elegant, but most of all timeless, bulletproof, and great sounding! You can plug just about anything into this amp’s input with good results. This circuit features:

  • 8 watts per channel
  • 1 GZ34 rectifier tube
  • 2 6SL7 preamp tubes
  • 2 EL34 power tubes (in this circuit these tubes are interchangeable with KT88s, 6550s, KT66s, KT90s, EL37s, 350Bs and other octal based output tubes with no modifications)
