Ramsey SHA1C Stereo Headphone Amplifier Kit

Summary: Great sound
Review: I use this amplifier with Grundig S350 radio(line output) and Sennheiser HD280 headphone. They form a great music system; it seems to me that all of the three devices have quite a flat response.
Before you use it, you hvae to spend about an hour putting the components in the PCB and solding them. It took 20-30 hours to burn in. One thing I feel uncomfortable about is it is in lack of a battery compartment; if you want to install a 9v battery you have to unsrew two long screws and open the cover.
