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). Here I'm offering you a fully assembled DC Blocker in metal case. Dimensions of DC Blocker: 122x66x140 mm. (WxHxD). Weight: ~ 0.85 kg. For detailed description of PCB please see my other listing:PCB for DC trap/blocker/filter for toroidal transformers (toroids) DC Blocker is built with following parts: - 15 000 uF EPCOS capacitors - high-voltage diodes HER605 - 10W power resistor - WIMA MKS4 400VAC capacitor - MOLEX 3-terminal connectors for AC input/output - Schurter IEC power inlet with fuse - Schneider AC Power outlet (Schuko type) - steel case powder coated in black - 4 small rubber feet underneath the case. A surge protection with 250V rated varistor and 6.3A fuse (Schurter Slow-blow type) is incorporated at the AC input. All parts used are freshly obtained from reliable sources (Mouser, Farnell, Digi-Key etc.). The DC Blocker can be tweaked at user request with different AC outlets (French, UK or US types), different surge protection threshold (varistor's voltage or fuse value) or different capacitors' values/types at no additional cost (in most cases) - just send me a question. What the buyer will receive: The package will contain 1 pcs. FULLY ASSEMBLED and tested DC trap/blocker/filter for toroidal transformers (toroids) in steel case. I always ship with Registered Airmail, so tracking number will be sent after postage. Combined shipping with other my items is welcome - just use "ask a question" at the bottom of the page or "request a total from seller".
