MD-CORE WIDE BANDWIDTH TRANSFORMERS

Breaking news to the audio world!. Now available, Push-Pull transformers that exhibits ultra wide bandwidths. A breakthrough in transformer technology, these MD-Core transformers has taken performance to a new threshold. They have outperformed the familiar toroids in all applications. All transformers are custom made for primary & secondary impedances, screen taps and feedback windings.

Special two chamber high end audio transformer for best primary balance. These audio transformer are designed for high end push pull tube amplifiers. Very low flux, wide bandwidth, lowest distortion, low copper resistances, best materials, grain oriented core material guarantees highest performance. Best manufacturing and exact dimensioning provide outstanding sound results.
