Repairing mid-'80's Aiwa HS-J09, 9, 600, 10, 36, 360

I think the HS-G08 uses a different mechanism for transport and reversing but that may be an area to look at with the HS-J08 which is the more severe of the two units with this "pulsing" problem.

 

I suspect the same, although don't know how I could make a list unless I go through each service manual individually (some of which are not even available).
If you have any hints of how we could make such a list it would be welcomed.

As far as the G08 goes, logic control mechanisms would expect to have a different code even if they're based on the manual one.

 

My Aiwa HS-J10 has soft touch buttons for forward and reverse, and it has the 2ME-7 mechanism. This makes some sense because the models with mechanical controls, like the J9/09/600 use electrical switches as part of the tape direction switching. Probably they control motor rotation direction and head track switching.

From what I understand of the mechanism, reversing the motor results in the gear assembly A clutch function moving other levers.

So to complicate the matter there are models with a mix. I don't know how to curate accurate mechanism lists, unless Aiwa had such data somewhere.
