28ASR project - the foam sound deadening pads had turned to black sticky gunk, so I decided to take the whole thing apart to clean it and to learn about it. Photos were taken to document and refresh my memory about how things were put together - I strongly suspect I didn't take enough photos and will deeply regret it.....
