My Aiwa deck that needs new belts decided to start playing tapes again (I guess the belt was in contact again). It needs an azimuth adjustment to play tapes made on my Sony deck. Anyways Im told one uses a nut driver to do the adjustment on Aiwa decks. Problem is I have not been able to find a driver small enough for these nuts. I have been able to use a 4mm ratchet socket which works. But the one nut on the bottom right is the one I need to adjust. The problem is there is a metal bar in front of that lower nut that prevents the socket from getting in there. That metal bar is part of the cassette door frame. What I need this deck to do is to engage the play mode without a cassette installed and the door still open. Then I can get at that nut. But it seems Aiwa (unlike my Sony deck) doesn't allow this cleaning mode to engage the heads and capstans in play mode. I tried power up the deck while holding the play button, pause button, eject button, etc. Nothing seems to do this.So tell me- how does one get at that lower right nut if this stupid metal bar is in the way?
Follow Ups:
Hello.I suppose you have tried to pull up the door cover (the visible part of the door). Usually you only need you r hands to remove it.
Once the cover is apart, In most of the decks I have you can adjust the azimuth. If the head is behind a metal or plastic bar, that bar has holes or doens't hide the screws that hold the heads.
I made some photos in another thread. Take them as example:
I'll post some photos. Maybe that will help explain this better. Oh and yes the door cover is off.
http://www.geocities.com/shpickering/Aiwadeckassembly.jpgHere above is what the head assembly looks like while in play mode. Its not much easier when the door is open either. It looks like I've already done some damage to the nut trying to adjust it.
Question- is the lower right screw even allowing to be adjusted? I tried moving the upper right one and it seems to be locked into place. It wouldn't budge when turned.
lower right screw could be for the adjustment of tilt/heigh. But I'm really not sure. In my sony deck is over the azimuth screws, not under them.
As I was told it shouldn't be touched unless output is not equal on both channels. But it's anyway, adjustable.And looking at the screws through the holes... are that phillips screws? They doesn't look like screws but threads with the central part of it of black plastic to avoid undesired rotation.
The Aiwas have a thread which a nut is installed. This nut is what makes the adjustment. You need a nut driver to do this, but I was able to use a 4mm socket on the ones I could get at. All I know is the left screw (only one on that side) is not giving the range I need to get the high end back.
The left screw is next to the recording head.
If the one on the right is adjustable , it will produce a wider movement on the playing head, which will help to get the high end back
I found it. It was the upper left screw hiding from view. That did the trick. All I needed was a tiny screw driver. Problem is turning the other two nuts I wonder what I changed in adjustment? I would have left them alone had I seen that inner screw to turn before. Anyways the belt finally slipped so I can't play cassettes at all now. Just in time to replace them. Lucky I have parts already, but Im sending the deck in for that.
Too add I tried a set of tiny needle nose pliers and those things could not get in there and get a grip on that lower right nut. I need to loosen it. It makes me wonder why Aiwa made this nut so inaccessable to adjust. Anyone ever adjust Aiwa decks?
If anyone is currious- the Aiwa deck is a XK-S9000 cassette deck.
