In my amp there is a NJM4580 from JRC, one half being used as DC servo and the other as an input buffer for the amp. It is dead because of its zener supplynow being a short to the positive rail.
I cannot source any NJM4580. Is there a suitable replacement which can do both functions equally well? NE5532 (which I have plenty) maybe?
Regards

you can use a wide range of dual op amps
I would try the follow: OP-275 (Analog Devices), OPA-2132, OPA2604 and NE5532 (last three from TI)
