Welcome to our website

Marble Amplifiers are built by a small company: FnS Tube Technologies.
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, with special emphasis on American amps from the 50’s and 60’s. We respect the legacy of these great amp builders due to a long tradition of repairing and customizing almost any kind of amplifier.

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 20 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 serious musician 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.
