I just dragged it into the workspace here at work. It's EASILY half the weight of the Counterpoint. A couple more caps and some tubes and I think we'd be there.
Appears to be from 1974, based on a sticker I found inside. 200WPC in 1974 was significant, as you PL fans know. It also has esoteric knobs and buttons on the front I have no hope of ever understanding. Inside, it's a bit of a mess! I guess this is how things were done in 1974, but by 70's vintage Japanese stuff is a LOT nicer inside.
The gentleman I got it from is quite nice. He's "in the business" so I'll have to follow up with him again. He bought a truckload of gear from a deceased audio engineer. I think he said he got six Revox tape decks, and at least one Otari. (maybe two). I didn't have time to chat further, as it was late, but he's sitting on some good stuff it seems. He paid zero for this amp in that deal, so he made his money back.
Anyway, all the fuses are good, and I don't see anything obvious, other than it appears the transistors (I guess- not the power transistors, which are carefully placed to overheat the speaker binding posts) on the left hand board appear to have gotten much hotter than those on the right side board.
