AIWA HS P08 Help needed. Autoreverse doesn't work

Hey,

I have a AIWA HS P08 in Good Condition. I replaced the belts and put everything together, but every time when I think it works, it works just for one day and the next day the Autoreverse doesn't flip to the other direction anymore.

Yesterday I got exactly the same issue. I controlled the whole board, soldered everything, put it back together and it worked perfectly fine. I went to sleep and the next morning the Walkman just played Side A and didn't reverse anymore.

If I press play the second time I hear that it gives the command (sound mutes for a short time) and the Direction LED gets a little darker in this moment but nothing happens.

yesterday a cable from PL2 was broken but after fixing that it worked… after a few hours it didn't anymore. The PCB looks like crap after desoldering, disassembling and put everything back together 10 times… it's like looking for a ghost. everytime I thought I found the issue it's back again…

I don't think that me and this guy become friends in this life :-( does somebody know this unit well? Nobody can tell me anything about it.

Cheers Tobi

 

Does the P08 use some variation of the 2ME-7 mechanism?

 

I don’t know the name of the mechanism, but I guess it is a Full Logic Version of the HS-P07.

But to be safe here is the manual:

So far as I can see, it does not use the 2ME-7 mechanism. So what I've learned won't be applicable.

 

I have a couple of these the HS-G08 and it's US market HS-G500. The G500 is perfect but the G08 has issues with the transport. Once it is working it reverses fine but sometimes the buttons seem to do something other than the functions they're supposed to do. If that happens the unit jams between play and Stop and it's goodnight. I'm reluctant to put any valuable cassette in it in case this happen. My work around is to always remove the cassette before pressing any of the soft touch controls. Then with the cassette door open I press the green microswitch down and then hit the play button several times to make sure it's switching from Play to Rev Play before putting in the cassette. So far this has worked for my HS-G08 without that door locking on my cassette.
