Valve Factory 1 Amp Kit Instructions
The new Valve Factory 1 Amp Kit will be a blast to play through and even more fun to build.
The VF1 is designed to demystify how tube amplifiers actually work. Our Lego-like, step-by-step instructions walk you through the entire build clearly and safely, whether you've been soldering for years or you're tackling your first serious electronics project. You won't just end up with a great-sounding amp—you'll understand why it sounds the way it does.
This amp is designed with a reduced-voltage design and smaller circuit, making it a safer, confidence-building entry point into tube amp construction. We've carefully laid out a path that even newcomers can follow in handling electrical components.
The VF1 carries less risk than a full-size tube amp, but proper safety precautions must be followed at all times during build and testing.
Nobody makes it easier to build an amp than StewMac.
