Guess the amp!

Breaking records is good?
Was cleaning this guy and figured I'd snap some pics. Can you guess who made it? Bonus points for the model. Hints, integrated amp circa 1980s. Sorry if I had to crop some of the images to hide anything that might identify it too easily. If no one guesses I'll add photos unless it proves too hard. Here's #1

I don't know the model, but it looks like a Sony to me.

Dumont- first with the finest in television.:yes:
 
Yamaha M-something. I have an M-65 with the exact same heat sink but with a square El transformer instead of a toroid. This must be newer. M4?
 
Sony, not a STR-GX10ES. No copper to be seen, at least I didn't see any. GX9? Wait you said amp. TA-E77, N77, N80, I think late 80's or early 90's ES series.
 
haha, hilarious Whysakit! It aint ES from that is for sure, well at least not real ES.
It's remote controllable, basic and cheap and weighs about 8kg, dishes out 60 watts per channel and you can bet that potted transformer is not a toroid, merely a normal transformer potted in a round case to look like a toroid.
 
Yamaha

Looks like the inards of a r-9 reciever ,but since its an integrated I guess somewhere in the A-xxxx series.
 
It was worth a guess, my ES has that same look to it when I opened up to clean it (it wasn't that long ago). That heat sink is exactly the same and the layout is along the same lines. Actually now that I think about it that Transformer is all wrong. Mine has a wierd looking band that goes around it and looks like it is rusted, it also says ES (DOH!). I do admit that I am no expert.
 
Yep, its a Sony, didn't catch the Sony on that PCB until I posted this, TA-AX455. It was actually part of an integrated system, and I think this one was from around 1986. As to whether or not it's a real torroid or not I didn't remove the case to find out, though I've got another piece of equipment with a similar thing and it was a torroid so is hard to tell. It's not too bad overall, even uses 10,000uf caps.
