BMW E36 Harmon Kardon Amp Teardown

A short video of the result of a teardown of my largely non-functional Harmon Kardon amplifier from my 1998 BMW 328is.
The amplifier is designed around the TDA8563Q integrated amplifier module, which is longer available as of 2015. There may be pin-compatible replacements for these parts but I haven't searched for them.
The board is a simple two layer design and could be reverse engineered, but the process would take time -- something I don't have in abundance. Considering I have a ton of new equipment ready to be installed I'll probably not bother to reverse engineer and troubleshoot the design, though I do plan to keep the unit for possible later experimentation.
