    Hello all, I have just wrapped up a major restoration on a newly acquired SX-1050 that had a very rough past to me and had arrived in very rough shape. The unit had been sitting in the attic of a small stereo shop near my university for nearly 27 years, according to the repair tag's date of...

    Sansui AU-999 recap and mod journey

    I had acquired this fine 999, which ultimately led me here to this forum for research, and it wasn’t before long that I became a Sansui fan. I always wanted to learn more about electronics and stereo repair, and it is quite serendipitous how this all happened. Not to long after that, I got a...

    QX-949 repair

    Long story short I have a pioneer qx-949 with a weak right channel in stereo mode on AM/FM/phono inputs; there is essentially no bass output and treble sounds off too in the weak channel. AUX input works perfectly in stereo mode (no weak channel). To make things more interesting, when I flip the...

    Sansui Au-666 Error on Schematic PNP Driver/Output Transistors. "Correctly Drawn/Fixed"

    So I noticed an error on the AU-666 while tracing all my wires back throughout the entire amp. Based on evidence left behind, this was probably a revision Sansui never fully finished in the manual. They show the collector of the "TR813" 2SA537 driver transistor going to Pin 8 on the Driver PCB...

    Hi AK members. I own 1030 for about a year. Bought it for 130EUR and enjoyed so far. I knew it was in original state and untouched inside. Only lamps were changed.
