Up for sale here is this set of 5 brand new knobs. These are beautiful brushed-aluminum knobs and look amazing. They will fit the Sansui lever knobs on the QRX-8001 and QRX-9001. These are NOT for the pushbuttons, just the levers.
These are almost identical to the old lever knobs, but they are a little shinier. I would probably just replace all of them if you want them to match. These measure 16mm long and 7.9mm in diameter. The old lever knobs measure 15.3mm long and 8mm in diameter, so these are almost identical. These will fit the pushbuttons as well, but they are not as wide as the old ones. These have a 3.3mm square hole, so it's about 4.3mm diagonally. These have square holes, but they will fit the lever shaft perfectly if you line up the shaft diagonally in the knob hole.
These are for the lever knobs, NOT the pushbuttons. They are not the same size as the pushbuttons.
