Thanks very much for your reply, Guy, that’s good info! Dad been looking for the pin wiring info and after my searches came up blank I ended up buying a 5 pin male to dual female phonos lead.
Unfortunately the input signal seems strong so unlikely there is a wiring issue.
And also found the 7002 manual now – thanks again! Had been pressing buttons a little haphazardly but that now suggests Tape + P1 to activate Aux; unless anybody knows of a key combination wrinkle on the 7000 I guess the problem must be on the inside? Anybody have any clues? Or even a basic instruction for how to open the thing up? 😮
Again many thanks for any help!
