All BEZ made transformers are brand new. We adopt Japanese made high quality H10/0.35EI non-oriented silicon steel sheet and enameled oxygen-free copper wire windings, special used for Hi-Fi components. Separate layers of pure wood pulp insulating paper and multiple segments design, plus our advanced technique on insulation and moisture proof, BEZ made transformers have high quality of performance on amp sounds. Stainless steel transformer cases also provide an outstanding appearance. So far, our products have been sold to America, Australia, UK, Japan and other countries. No matter what the occasion, we take sounds to heart!

PS:

Types of transformers should be told to us when you ordering.

Types include horizontal (outlet hole on left or right), vertical (outlet hole at the buttom), and embading (no outlet hole).

Please make sure you give the information to us. Power transformers can be customized.

Iron core (steel sheets) width: 32mm (lamination thickness 1 cm, 0.45 kg), $10* USD per kg.

Iron core (steel sheets) width: 38mm (lamination thickness 1 cm, 0.64 kg), $12* USD per kg.
