Custom fonolab Moving Coil Step-Up Transformers
Our clients often ask for various modifications and options to expand functionality or simply to make their order original.
Below we are presented some models released in limited edition or in a single copy.
The common thing that unites our products is the following points.
Traditional hand and CNC made parts are standard.
The custom-made aluminum/copper case equipped with high efficient internal damping materials.
The parts are assembled with the stainless-steel non-magnetic screws to minimize the influence of the magnetic distortion; thereby the clear sound has been realized.
Internal wiring made by OFC shielded high grade cable.
Exotic wiring upgrades such as solid core silver wiring are also available.
We use high quality brass RCA connectors (gold plated or rhodium plated) with Teflon insulation.
The transformers are thoroughly demagnetized and checked in our laboratory.
