   High Voltage OP amp

   From: trevor@rageaudio.com.au   
      
   I am servicing a power amplifier which uses a dual, 8 pin DIP OP amp.   
   Unfortunately, the rail Volts on the OP amp (LF353) is +/- 22 Volts. I   
   am familiar with this particular amplifier and OP amp failure is quite a   
   frequent thing. I need a suggested replacement. I am quite happy to use   
   single OP amps, or SOICs, as I can employ a Brown Dog carrier to adapt   
   to the existing layout. Ideally, a bit more performance over the LF353   
   would be nice.   
      
   And no, it is not possible to drop the rail Voltages. They must remain   
   at +/-22 Volts.
