Onkyo M504 Stereo Amplifier Relamp and Basic Inspection etc.

In this video, I re-lamp an Onkyo Integra, model M-504 stereo amplifier. In addition, I perform a preliminary inspection and some complimentary cleaning of dust / dirt from the interior and exterior. During this process I cover specifics that some may find interesting and perhaps useful.
