Ew, god, restuff the cans? I hate it when people do that. This is a tool, and a beautiful piece of engineering, not some wanky painting or something - its beauty comes from the practical, functional design, not the specific shape and size of the capacitors... Hiding nice, modern parts inside crusty old ones seems to me a bit of an insult to the spirit of the engineering work that went into building this in the first place. Do you think, given a choice between a modern capacitor from 2014 and one of the caps that were available in the 1960s, the original engineers would have chosen the latter?
