In the picture of Stax (Museum) Studio . I own the 280 2 track in the picture. It was found in the back of a local Memphis studio at which Bobby Manuel (Stax Engineer) did sessions. It came out of the Stax bankrupcy sale. Bobby did verify this was one of two Stax 2 track mix down machines. This is the one that was used to mix dock of the bay ,FaFaFa and many other Otis Redding hits . A true piece of history. I put in on loan to the museum for everyone to enjoy Where it should be).
