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 without traditional high-voltage circuitry, making it a safe, confidence-building entry point into tube amp construction. We've carefully laid out a path that even newcomers can follow in handling electrical components.
Nobody makes it easier to build an amp than StewMac.
