Default Revox A77 really wide stereo .

I have yet another A77 ,(man I`m bored of these ..lol) , thats got a strange issue . I`ve calibrated it and the numbers all came up right , but , when I play back and A/B input and tape out , tape is much much wider sounding (stereo wise) than the input , its not the input card because I`ve swapped that out (tried 3 different ones) , anyone know where to start ?

Is yours the one with inbuilt amp and speakers? If so, check the brown-black and red-yellow speaker wires are correct. There is usually a handily placed wiring diagram inside the cabinet!
