This is a miniature headphone amp to add to projects for monitoring purposes.

The board is approximately .8 x 1.125 inches and contains a stereo level control. Each amp is a MC33083 op amp driving a bipolar emitter follower. The biasing diodes are thermally coupled to the output transistors. The output is coupled with a tantalum 47uf capacitor to the headphone. Each channel should be able to do about 300mW into a 55 Ohm load.
