    To anyone who may have info on this model. I recently recapped and fully restored this AU-D7. It had 2 blown output transistors,2 drivers,the bias transistor,the bias resistor, the bias and dc offset pots and a couple small transistors on the driver pc that were bad and a few .5 watt resistors...

    modifying a Sansui AU-D7

    Greetings everyone. Does anyone have suggested mods to an AU-D7 which would make it sound warmer and more tube like? I have searched and did not see any mods for this amp, but perhaps I missed one or two. Thank you for your help.
