    AU-919 would be my choice. That was my favorite era of Sansui.

    For me AU-919 every time, but eventual choice might depend for others on available space, and their need/requirement for a tuner.

    Other things might also come into play, the rather dour looking black faced AU-919 (part of its attraction for me :bowdown: ), vs the glitzy lit up face of a large receiver is irresistible for some people. :king:

    is the AU 919 on the "still safe to acquire" list due to its unobtainable parts that may blow up? There is one near me for not that much dough....

    I would think so, the most dificult part to get is the outputs, but you can get them NOS (expensive) or adapt TO-3P... Servicing it on the other hand seems better to be left to very experienced techs.

    Nor do I. :)
    If it has already been 'blown up', and repaired, it is unlikely to have original OP transistors - thought by many to give the AU-919 its special sound.

    This amplifier is really special, if misguided folk continue to use one in original condition, then oblivion for the unobtanium OP transistors is only a footstep away. Although with some difficulty, conversion to TO-3P alternative OP transistors, can/will restore that lost 'something'.

    the 919 hasn't been blown up yet , have a few issues still as in the selector switch.. when changing it up or down it has popping noises and after warm up say 2 hours i hear a slight ground noise , like a hissing hum ,hows that for tech talk lol . phono section recapped , power board recapped , eq board recapped , all black flags changed even tho only 2 were bad . the power transistors were replaced also . this amp sounds amazing just need to get these few bugs out of it, not myself a tech will have it back soon .

    I was having popping issues coming from the flat amp. The small transistors give problems and probably should be replaced wholesale. Here's Hyperion's instructions:

    I've had an AU-919 and an 8080 and heard someone else's 9090DB. I sure wish I had the 919 back.

    I don't want to promote any commercial activity here but.... It seems that an AK member, Kale, is selling some AU-919 NOS parts thru that famous online shopping site.

    Between the two of them ? Never heard the AU-919 but I believe they might sound like the Japanese Alphas so, in this case, it's just perfect sound ! IMHO.
