QVATTVOR Symmetrical Balanced Toroidal Step-Up Transformer


fonolab. MC step-up transformer has been carefully designed and manufactured in the Czech Republic to satisfy the highest interrogates for musicality.


Today, when balanced circuits have become the de facto standard for high-end audio design, we are proud to present our vision of transformer amplification for MC cartridges.

Matched pair of Tamura permalloy toroidal core transformers is used for each channel in fully balanced topology.



Transformers which has both ultra-wide band and ultra-small distortion with the possibility of connecting cartridges with an impedance of 3 and 40 Ohms. 



Traditional Tamura sound in balanced design with modern shielding and damping technology brings a new level of ultra-low noise and high resolution.

QVATTVOR features:


Permalloy toroidal core transformers (specially manufactured by Tamura Corp.) is used for each channel


The custom-made aluminum/copper case equipped with highly efficient internal damping materials


Stainless-steel non-magnetic screws to minimize the influence of the magnetic distortion; thereby the clear sound has been realized


LC-OFC is used for the wiring material


High quality Neutrik XLR and Gold-plated brass RCA connectors with Teflon insulation
