This is it! The most complete Marantz restoration how-to video on RU-vid!
Please read this. Only use this video to help you restore your Marantz or other receiver if you're very confident in your abilities. I'm not responsible if you damage something or hurt yourself. Most importantly, understand that this is MY take on doing a restoration. Others might have different ways of doing things, others may also think things in this video are just plain wrong. This is a long video, but there's probably things that I forgot to mention in places.
The 2215B was not a good choice for this video in some ways since it has some pretty unique differences compared to the majority of vintage Marantz receivers. I have restored a 2250B video by video in the past, so I'll link those board-specific videos here:
