Now I have the second Sharp GF 9000 this was in a very bad condition because I had to clean a lot as you can see it has paid off, unfortunately 2 important towers are missing for the slider, and he only goes to battery of him trying to operate on AC power led to the total failure in the apartment oh w
ell one can not have everything such a factor is quite ok 
...working on mine as we speak...such an awesome looking box, can't give a judgement on the sound yet as mine needs a bit more work before it will (fingers crossed) boom! 

I have never tried that
