This link was sent to me by an ex-sansui engineer this week. It's a youtube video (in japanese) showing ex-Sansui engineers and their "Sansui products restore fab". Apparently this made it onto the TV over there. Not much tech activity in the video but still some good amp eye candy. I notice that their solder sucker is a lot better than mine. Also, I notice when they removed dust they didn't blow with compressed air (which can force dust into parts where it wouldn't usually get to), but used a brush + vacuum.
