    Hey everyone,

    I just had a chance to measure frequency response of the breadboarded amplifier. Frequency response appears to be pretty good, with a bit of roll-off in the very low frequency range ( > 60 Hz). 

    Below are some captured waveforms, from an OWON SDS7102V. The red is input, the yellow is output.

    Please check back for updates. Questions and comments are always welcome.

    Hey everyone, 

    This is the first build update for my simple headphone amplifier. This is a fairly quick, simple project based on the popular CMoy headphone amplifier design. I have opted to use the TL082 Opamp due to availability, cost, and general quality.

    I have breadboarded a single channel, just to verify my design actually worked. So far, it does. I will finish the second channel soon, and begin taking some measurements on the scope to further analyze the design.
