This unit has been cleaned and bench tested in the ProShow service department. 115 Watts at 8 ohms, as spec'd. A nice example of a vintage audiophile amplifier with extremely low distortion.

Ships double boxed and well packed.

The DH-220 circuit is a refinement of the DH-200 design, a Hafler landmark which has achieved worldwide recognition, and has elicited glowing reviews since its 1979 introduction.

As in the DH-110 preamplifier, particular attention has been paid to component quality, using polypropylene or film capacitors wherever feasible, for example, for superior sound.

Combining the latest power MOSFET technology with uniquely simple and effective circuit topology reduces distortion of all types, and at all power levels, over the full audio frequency spectrum, to the vanishing point.
