DC BLOCKER

DC blocker for toroidal transformers.

This filter will be very useful for anyone using audio amplifiers based on toroidal transformers.

This project was created to block the direct current occurring in power networks, which adversely affects the operation of toroidal transformers.

Due to core saturation caused by direct current, the transformer starts to emit a loud buzzing noise and heats up. In order to avoid this, a direct current filter was developed.
