eBay Rear Window #2

This may not be as drool-worthy to the rest of you, but I've got a real soft spot for the 500 format, and see the 512 as the champ of its type. Ten of them, racked and powered, in a row? All the better. Sure, ten Mono Gamas would look cooler, but this'll do just fine for now.

It's worth noting that the auction, of course, in keeping with the theme of the "Rear Window" posts, is only for one of the preamps in the photo above.
