2NRG The 2NRG contains 3 custommade transformers, each with 2 separate windings. Two outputs have 200.000uF capacitance, the third 100.000uF all with rectifying by the use of ultrafast and precise diodes. All in all the 2NRG has no less than 510.000uF in the form of 51 custommade capacitors. The 2NRG supplies the B-275 preamp and the forthcoming B-475 CD player.
