Default Sony TA212 info needed.

Hi guys.

I just got myself a "brand new" Sony TA212.
New for me because this little thingie was passed through the able hands of a real audio "mastermind" (pun indended).
He kinda changed lots of components with some locally (former glory) parts that are ... well ... kinda lackluster today. Maybe 30 years ago ... maybe ... but now these are just bad.

Since this baby is a cutie i'd like to restore it to it's former glory (or better - soundwise) so would be really thankfull for any schematic and/or BOM or whatever may be available.

Thank you.

Peace.

It does look very nice. I can vaguely remember these from when they were new.

Not sure how much former glory there is to restore, though. How good was it back in the day? Even a perfect restoration would just give you a reincarnation of a very old design. It was only 20W per channel to begin with, or even less according to some sources. One gives it as 12W at 3% THD!

The cabinet is far too nice to go to waste. Why not just replace everything inside with modern circuitry? Kind of like dropping a 640bhp LS9 engine into an old Corvette.

This amp has a microphone input, and this was from before karaoke was an English word. Amazing!
