The JBE 4001 was exactly the same specification as the 3001, with the exception of its black acrylic plinth. Just like the 3001, it would be ordered with the distinctive JBE platter, or a more conventional platter.
4/4/2012 - Email contact from Ronald (from Netherlands) who was asking whether I could identify his JBE, which had been sold to him as a 7001. Initially I was doubtful it was a 7001 and felt it was yet another JBE prototype. Following the brochure information sent to me by Ronald some months later we can now identify this as a JBE 4001, although the plaque on the turntable would suggest subsequent modifications.
