Welcome to our website

Marble Amplifiers are built by a small company: FnS Tube Technologies.
We strive for Harmonic Perfection by Tradition™. We feel that the Soul of Tubes is captured best by working in the tradition of the great amplifier designs of the days gone by.

We respect their legacy due to a long tradition of repairing and customizing almost any kind of amplifier, with special emphasis on American amps from the 50’s and 60’s. In addition, we can add to their designs by careful consideration of players’ demands, a craft that many amplifier brands seem to have lost. In the span of 15 years, we have developed 3 different series of Amps, catering for the needs and tastes of serious and professional musicians alike. We have combined the craft and workmanship of our workforce to the best of our ability to provide you with the finest hand-built amps for the True Player™ at a competitive price, and with good looks to match. Do not hesitate to get in touch with us or our dealers.Let your ears feast on the Soul of Tubes.
