The Hafler DH-120 is a very high quality 60 watts-per-channel MOSFET class AB stereo power amplifier. MOSFETs are solid-state devices that work on principals more similar to vacuum tubes than bipolar transistors — and it sounds great! This 30-year-old sample easily put out 77 WPC continuous and 118 W burst power into 8?.ts a traditional class AB linear power amplifier in a sheet metal steel case. It has four power MOSFETs (2 per channel) in TO-3 packages mounted to two big, anodized aluminum heat sinks on opposite sides of the case. This also comes with 19 Standard rack mount plate.SpecificationsPower output: 60 watts per channel into 8?

Unit in good condition with a few scratches on front and top, 60 watt into 8 ohms X 2 channels, 10 hz - 40 khz, 120 Vac.

I purchased this a while back and cleaned it up and repainted the face because it was scratched up. It works perfectly.
