    Hello all,

    The I.C. is an 8 pin DIP and has the number 'A2211', a date code and
    what looks like a backwards 'R' followed by a 'U'. While the repair work
    didn't involve the I.C. this time, I'd like to find the datasheet in
    case I have to deal with it in the future.

    The manufacturer of the amplifier will not supply a schematic until the
    unit is out of production (very common for manufacturers of class D
    amplifiers - some never provide schematics). It looks like it's being
    used as a buffer or possibly an inverter (all signals look identical).

    Any help would be greatly appreciated.
