Here are mine, they all need restoration.
TU-666, found at a junk shop
5000x, does not have the updated amp boards, blows the left channel fuse. I'm debating whether this is a project I want to take on, or find someone who knows what they're doing. If there is anyone near central Mass who does, I love to talk with them.
And lastly, on top of the 5000x, a Lafayette LR-200A. I got it at the same time as the 5000x, and the rumor was that these were made by Sansui. I think there is a family resemblance. As near as I can tell from my research, it makes about 8 w/ch. There was a Sansui, that looks a lot like with the same power output. It sounds awesome! Drives a pair of ESS speakers in the man cave surprisingly well.
