We provide hundreds of Toroidal transformers, mostly from the high quality TOROIDY and TALEMA brands. Several other brands are listed as well.

Talema provides potted versions in certain ranges for lowest possible mechanical hum. Larger ones in a strong PVC case, smaller ones (<50VA) in PCB versions as well. They are not shielded though!  TALEMA Catalog here

Since January 2021, we also represent the Polish company TOROIDY, which produces the most fantastic toroidal transformers, standard or shielded. There are even potted / shielded versions in polished steel. Even the price is very interesting, even though it is an EU-based company with its own high-quality production facilities. This brand offers all power transformers with single or double secondary windings. Just about all possible secondary voltages are available. Click on the article and find more details. Choose the number of secundary windings and voltage (s) and place your order. The desired voltage is not in the list? Choose "other" and indicate the voltage in the comment line on your order form. Above 50V there is a surcharge on delivery!
They also manufacture all kinds of toroidal transformers for tube electronics. If you are interested in that, please contact us. Power and output transformers are available in several types and sizes.
