    Recent finds in resale stores

    I found these at two different local thrift stores but didnt buy them since the prices werent really set for a bargain hunter. The Sansui SP-X7900s above were in great shape but $250. for the pair seemed exorbitant for 30 - 40 year old speakers. They did really look cool with the 5 way speaker...

    Sansui AU-8500 Scratchy Background Noise on Preamp Section

    Hi all, Picked up a Sansui AU8500 few months ago for an extremely nice price during my self-imposed no-buy drought. A price too good to pass up! Unmolested in terms of upgrades, but dirty as hell on the inside. I did my best to clean the interior of the chassis and controls with many Q-tips...

    Hello all, does anyone have a full list of caps for replacement in a Sansui 500? (not 500A) I know there are discrepancies between the schematic and reality so I thought I'd see if anyone had waded through any of this. Much appreciated.
