High End Toroidal Output Transformers
In 1983 Vanderveen started the development of high end toroidal transformers for audio signals, especially intended for vacuum tube amplifiers. After many years of research and production a wide range of many transformers was the result. Complete description of this range plus all the available literature will take too much space of this site. Therefore, go for more information to the three centers of worldwide production and sales: www.ringkerntrafo.nl (for Europe) and www.plitron.com (for Nafta and Japan) and www.trafco.rs (for East Europe). Also read the book“Modern High End Valve Amplifiers ...” by Menno van der Veen. It contains very detailed descriptions and applications of these unique toroidal transformers.

MC-10: The high-end step up transformer for moving coil cartridges
Gramophone discs surely have not left the high-end scene. Their quality is still unbeaten. The new Vanderveen MC-10 step up transformer is designed for optimal enjoyment of the goodies of the disc: pure quality of sound. The MC-10 transforms the small output voltages of a moving coil cartridge into a 10 times larger voltage for direct connection to the MM input of a pre amplifier. The frequency range and linearity are superior, while the MC-10 can be matched to any MC cartridge. Click here to download all the technical and practical details of this special transformer.

VDV-GIT80: The universal output transformer for valve amplifiers
This web site contains the description of an unique project, totally based on this special EI output transformer. Go to “Project” for more details. The output transformer is intended for valve amplifiers with output powers ranging from a mere 5 to a maximum 80-100 Watt. Its windings are arranged in an universal manner, many primary and secondary impedances are available. The core is annealed in a special process, resulting in a very mild and friendly overload behavior; guitarists will love this sound character. In high end audio applications the extended and undistorted low frequency range is remarkable. The smart construction of the transformer results in a low price.

VDV-POW80: Universal power transformer for valve amplifiers
With its many primary voltage taps, this power transformer is happy all over the world. Two secondary windings of 270 V each deliver the high supply voltage. A 50 V winding is intended for the negative control grid supply (to set the quiescent current through power tubes). A 6.3 V winding of 4 A delivers power to the filaments. Together with the VDV-GIT80 this power transformer is the ideal combination for many valve amplifiers with output powers ranging from 5 to 80-100 Watt.
