I've got one - trouble is I would want a decent donation for it. The radio was working fine when I took it out.
The cassette player plays for about two minutes perfectly, then all the sound goes into one speaker. Eject the cassette and put it back in and it plays fine again for a short while, then only out of one speaker again.
Guy at the stereo shop said it just needed the tracking sorted he thought. However, I decided to fit a new unit into my 260Z.
I also removed the switch that sends the aerial up and down, so I can use it with the stereo I now have fitted. So you would have to fit another or do away with the electric aerial.
Otherwise it is in very good nick. Can email pics if you want to see it. PM me your email address.
