I have a chip I can't find a cross-reference for in any of my catalogs.
It is a 14-pin DIP marked as follows:

 |  |  |  |  |  |  |
---------------------
|     2058D         |
|)                  |
|   JRC 4535        |
---------------------
 |  |  |  |  |  |  |

The chip was removed from a car stereo subwoofer assembly made by
Matsushita and installed in a 1986 Mazda 626.  It is probably an
op-amp array of some kind.

Any info on this widget would be greatly appreciated.
