AU777A Died

[Woody MacKay]

I am looking for a detailed schematic for the AU777A Sansui Amplifier. This unit has served me since new in 1970 with fantastic audio. I use a pair of Speakerlab K homemade corner horns. I plan to replace all caps and transistors as needed. Thanks Woody MacKay woody.mackay@gmail.com

Again as suggest go over to the Sansui forum. There are a number of very qualifies guys that do restorations over there.

That is a nice piece. However those 1970s vintage SS units are clearly at the end of their life and in need of a full restoration. Unfortunately when "we" let these get to that point and they blow, they tend to take out more parts than we wish.

This was one of Sansui's better units so it is worth the cost of restoration. But it will be in the $600 range, Then again you are NOT going to get anything this good for that kind of money. And after the restoration it will sound FANTASTIC and most likely out live YOU!!!!

Good luck and enjoy.
