Hey guys. So yesterday I ran into about the best deal I've ever come across and landed this Mcintosh MC440. Now I'm pretty experienced with using and testing a lot of different types of amps but this thing is pretty special. I got it home, got it all cleaned up and want to put power to it on my test bench to see if she's alive but I convinced myself to hold off until I can talk to a few Mcintosh guys and see what they have to say. I test and mess with amps at home quite a bit using a standard 12v 18 amp computer power supply, sometimes two in parallel, and also have a small 12v lithium battery. Planning on just doing the standard process: Jump remote to B+, use an rca to aux into my phone as the source, check voltage on speaker outputs, and then put a couple small drivers on it. Is there anything that you guys recommend checking before I do so though? I've never had a Mcintosh and never really done any research into them before yesterday as they were simply out of my reach so I don't know the standard issues and things to look out for. Thanks guys, I appreciate any advice.
