I have had this receiver for a few months now and every thing seems to be working fine. Though I just spent a decent amount of money to replace/fix my speakers and just want to make sure this receiver is working properly while I wait for my speaker parts to arrive. I gave it a good little bath with some deoxit, but I don't really know how to tell if capacitors are bad or not. It seems like a pretty straight forward unit to work on but I was just wondering where should I start. I plan on checking the dc offset of my speaker terminals. I am somewhat comfortable with soldering and have a "parts" mcs receiver I am willing to practice on. Any suggestions are welcome, or if anyone lives in the raleigh area and wants to teach I'm up for that too haha.
