>>The new 130/131 uses CA3080 OTAs (like the 132 always did).
Dont the 130/131s use the PA382 Mine do, but i dont know what date they
were made.
My 132s certainly use the CA3280.
Anyway, on to what i was actually going to say:
Theres a lot of opamps out there. The ICs on the 130/131s are certainly
socketed (the 132 is soldered in). Theres quite possibly a drop in
replacement for those who are not happy with the performace of the opamps
used as standard.
For those of you who are having real dificulties, the CEM chips, although
probably no longer cheap, will, im sure, be availible somewhere, even if its
only ebay sales.
Anyway, i know very little about opamps. Maybee someone with more knowlege
could help suggest a suitable replacement for the PA382 / CA328x
