I can tell you exactly how they got the blond case.
In fact, I was just about to do this with my 8080DB.
The Sansui's came with the dreaded Vinyl wood grain on the case. Basicly, a sticker. All of you Sansui fans I am sure have a unit or two with a peeling corner. I just picked up an 8080DB in excellent condition with the exception of the case. Somebody had peeled off the top portion of the woodgrain vinyl, leaving only the tan colored backing in place. I had kicked around the idea of buying some new vinyl to replace it. The other day while I was working on re-finishing a Marantz cabinet, I decided to see what was under the tan backing on the Sansui. WOOD! Not a thin layer of wood veneer, but wood. I decided to peel all the vinyl off. I then hit a small section with sandpaper and since I already had the can of Deft spray out, I just hit the sanded section to see what it would look like. It looks exactly like the one in the picture.
I will be sanding the entire unit this weekend and refinishing it, but I think I will use stain to darken it up a bit.
It won't be original, but I consider it an upgrade to the sticker...I mean simulated woodgrain Vinyl.
