Description: Burwen DNF 1201 Dynamic Noise Filter DNF. This is electrically the same unit as the DNF-1201A -- only an alteration of the enclosure (see below). Excellent used condition. From the estate of an audiophile / vintage gear afficionado. Unit powers on and functions as intended. A beautiful example of a vintage DNF from the 1970s. The following are the same unit (same circuit), with only a change in outer case & name. Burwen sold out to KLH, who put their own name on the later units.
