    Need help with Sansui 5000a F-1040-1 boards

    Hello everyone. Just picked up a 5000a at an estate sale. Very clean unit but the left channel would blow the 4amp fuses. Opened the unit and discovered the f1040-1 boards.

This is true in Mono...

    Project: Sansui AU-717 (Restore / Rebuild)

    In the quest of vintage stereo, my adventure continues. Last weekend I found the Thanksgiving project. A non-working unit popped up, and I snagged it. The unit was a non-working sister to an AU-717 operational unit sitting at member @MtnBeachBum. Chris definitely was a AU-717 fan...

    Mr. Carlson works on a Sansui Sansui B-77

    Yeah....it's just a B-77 but there is good stuff here I think. (For a low level EE hobbiest like me at least.) He lavishes praise on Sansui engineers at the 9:33 mark. (And at a couple other points further along the way.)
