[sdiy] njm4560 op amp replacements

[Peter Blackett]

Dear Sdiy list,
I went to order some njm4560 op amps yesterday from Rapid here in the uk 
, but was told they were no longer available !
anyone happen to know which might be a suitable replacement ?
they are being used in medium end audio applications.
at least the pinout is standard and they are in a 8 dil package.....
many thanks for any help
regards Peter
