Nowadays the AC mains network is heavily polluted by various domestic appliances, industrial electrical consumers etc. This can lead to buzzy toroidal transformers (especially the power ones). Proposed DC trap (blocker, filter) will remove or at least lower the buzzing. Schematic is similar to this one used in well known Vladimir Shushurin's Lamm-1 amplifier. An article with in-dept explanation of how DC blockers work can be found on Rod Elliot's site (http://sound.westhost.com/articles/xfmr-dc.htm). Dimensions of PCB: 88x94 mm. PCB thickness: FR4 2 mm. Copper thickness: 70 um (2oz). Surface finish - Nickel Gold (ENIG).
