Opened Up: Home Theater Pioneer Receiver

Twas time to downsize and get rid of my stereo system. Something about a 35 lb subwoofer, two 10 lb speakers, and a 20 lb receiver strung together with over a dozen feet of speaker wire that got to me. Don't get me wrong, they sounded incredible. I had them since 2005 or 2006 and bought them with the idea of paying a premium for the "best" so the itch to upgrade would never touch me again.

There were a few times that I seriously considered picking up an extra pair of speakers to create a 4.1 system. Then I lost interest and didn't want to deal with it anymore. In my newfound desire to have fewer possessions, these giant, heavy items were getting in my way a bit.

Ten-ish Years Later
They were still working almost ten years later. I gave the speakers and subwoofer to someone on the cheap. The receiver, however, was thrown out -- it was still working when I unhooked it. Trying to sell a really old home theater receiver that didn't have any HDMI connections, had never been cleaned out, and probably had very ripe electronics wasn't something I thought was a good idea.

Instead of taking it out back and going to town with a club, the audio/video receiver was opened up. There were around six screws, some pushing and pulling, and voila.

The most shocking thing was that there wasn't that much dust. I was careful when dusting the grill on the cover over the years to avoid pushing dust into the holes. Turned out that I did a pretty good job. There was also a fan up front that I don't think I ever heard turn on over the past decade. My guess is that it only activated when temperatures rose above a threshold. With only two speakers to drive at pretty low volumes, that probably wasn't a big problem.

And nothing would be complete without a few shots from an infrared camera -- with the settings not properly set to create accurate temperature readings. Pay attention to the location of the giant heatsink.
