I have a JDM AU-X11 on the bench from another AK member for reconditioning. I have just about managed to correct the mistakes of the (Japanese) complete and utter numpty who worked on it before, it now works as intended. So the rest should be plain sailing, given that there is NO schematic and NO service manual to be found anywhere. I have already had some excellent support from AK member @SanthoshA with information to assist me in correcting the mistakes, thank you Santhosh. I really like the improvements on the internal construction as compared to the AU-X1. I'll post here if I find anything of note.
