NOTE!!!! This unit derives from the standard version with cable glands due to the numerous customer requests.

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 (https://sound-au.com/articles/xfmr-dc.htm).

Here is offered device capable to handle VERY HIGH CURRENTS (up to 30 Amperes!!!) assembled in a steel case – black powder coated.

Because of such high currents using a standard PCBs is not possible. Instead of that a 2mm. thick pure copper bussbars are used to connect the filter’s parts.

In order to carry such high loads the part’s values are upraised with 4 x 47 000 uF capacitors, 25W power resistor etc. For further description of the High-Power DC Blocker see here: High-Power DC Blocker Unit

The capacitor block is firmly connected to the bottom of the case with brackets and rubber sheet.

The input AC connector is Furutech FI-09 IEC Inlet, capable to handle up to 15A AC current.

The output AC outlets are two Furutech FI-E30 Schuko connectors located on the front panel along with the IEC AC Inlet.

The internal wiring is conducted with Silver plated wire OFC with PTFE insulation, 12AWG for Live and Neutral and 14AWG for Protective Earth.

Since Furutech offers its connectors in three different plating, the customer can choose between Furutech Gold plated, Rhodium plated and Furutech NCF.

!!!!!!NOTE!!!!!!! Since Furutech connectors are very expensive, I may not have them in hand at the moment. That’s why, contact me prior to order the unit in order to outline the timeline for unit’s manufacturing and payment.

There are 4 rubber feet on the bottom of the case which ensure that case will not scratch the underlying surface.

Unit’s weight: 2.50 kg.
