I have a few old master tapes which I would like to copy to another format.
I managed to get access for a while to an Akai 1800D-SS
I threaded a tape, turned the 'play switch' and for something like one second the reel turned in the correct direction, then it reverses and the tape starts becoming loose and unwinding.
When there is no tape threaded, the reel always turns in the correct direction.
I suspect that the issue is to do with tension, but I have no idea what to try next.
Anyone had similar problems?
