Can anyone identify the model number of this machine. Until yesterday this tape recorder was housed in BBC studios, howver they have moved to a new state of the art digital studio and this was one of the pieces of equipment I was lucky to get my hands on before it ended up in the skip. It appears to have been modified in some way, and it is a full track mono machine with a mono head. The XLR outputs on the back have also been reversed - what I would expect to be the line in, is the line out and vice-versa.
