Hey folks,

I have a SONY receiver, a fancy one from 1986, with lots of electronics
but the voltage conversion IC failed.

The chip looks like this:

            _________________________
            | (metal)               |	   
            |           0           |	   
            -------------------------
            |       LA5658          |
            >                       <
            | (plastic)     5H4     |
            -------------------------
             | | | | | | | | | | | |
             | | | | | | | | | | | |
             | | | | | | | | | | | |

has 12 pins and the company logo on the chip looks like the following:

             _______
            /       \
           /    /\   \
          |    //\\   |
          |   ///\\\  |
           \ ///  \\\/
            \       /
             -------

I mean three V's upside down in a circle. I couldn't figure out which one 
it is. The parts supplier couldn't figure it out either. So if anyone
has any idea as to what this IC might have an equivalent to or any other
information, it would be appreciated. 

Thanks,
