This Hafler DH-220 is a two channel Mosfet amplifier, which puts out 115w at 8 ohms, and is stable all the way down into a short circuit (0 ohms). It's a beautiful sounding amp, with a simple direct-coupled design. This is a popular amplifier for modification, and I have all the schematics. It can be bridged to produce 400w into 8 ohms, and it can also be used as a very nice headphone amplifier.
I'm asking $200 plus the cost of shipping, OBO.
