Stereo Question...

I generally don’t use the blog for things like this, but I figured this might be as good of place as any to try and get some feedback for my question. I currently have a mid-70’s era Marantz 2275 stereo receiver that needs some minor tuning up/work done to it. It’s basically gone without any maintenance during its lifespan and the 30+ years of wear and tear is starting to become noticeable. I am not exactly the best at doing these sorts of things on my own, so I was wondering if anyone out there knows of any place in or around the Kansas City area that does vintage stereo equipment repair and furthermore does good work, can be trusted, etc. If so, then feel free to leave a comment or shoot me an e-mail. Any feedback would be very much appreciated. Thanks!
