We are pioneering an interstage transformer-coupled advanced design that is new to the technology of sound amplification. This design completes our set of perfect tube amp solutions for any high-fidelity audio enthusiast. READ MORE:


“A very modern design approach to vintage inspired technology.” This was the American Tube Amp mindset when reinventing the single ended stereo tube amp. Our KT88 SE Stereo Amplifier is a very low distortion, zero-feedback amplifier in a class of its own. Our design methodology also prolongs tube life and the useful lifetime of the components and of the amplifier itself. You too can become a believer that pristine sound need not cost five digit figures.  READ MORE:


The American Tube Amp robust 60 watt ultra-linear push-pull tube-type monobloc amplifier was inspired by the venerable EICO HF-60. Of course our monobloc is a substantial upgrade to the EICO HF-60 boasting higher quality components and substantial improvements to the amp circuitry. We use a GZ34 rectifier tube for delayed high voltage to allow the output tubes time to warm up prior to the B+ voltage being applied.  READ MORE:


American Tube Amp is a low volume tube-type amplifier design engineering and manufacturing company and an audiophile and music industry product evaluation expert. One of our technical advantages is in the design and handcrafted construction of highly reliable tube amplifiers that yield a low distortion performance and that ensure long tube life. We apply the same rigorous standards that we implement in tube amp design to our product evaluations and recommendations.

Vacuum tube amplifiers made in the USA have set standards in tube amp technology and sound quality since the early 1920’s. What’s changed of this dynamic in the realm of tube amps in 2022,  a century later? Not much. Following this tradition American Tube Amp manufactures tube amplifiers inspired by legendary tube amp models of the past.  For example, our Monobloc design was fashioned after the classic original EICO HF-60 60 watt monobloc amplifier. Our vintage model inspired designs are true to the original architecture, spirit of invention and sound performance characteristics of the original unit that we have reinvented, but with significant enhancement, upgrade and modernization in the design, circuitry and components.  READ MORE:


If you don’t agree that tube amplifiers are necessarily part of an American heritage then at least you will confess that the vacuum tube itself was a MAJOR step in history that directly led way to modern electronics of every form. We personally feel that the vacuum tube and tube amps made in America have been and will continue to be a very important part of at least one aspect of American history – our sound. American Tube Amp is committed to help carry and elevate the long legacy of American made tube type amplifiers.  We also would like to share the origins of this science and craft.  READ MORE:
