The problem is I am in the U.K and we do not get NTE devices.
Thanks.
I'd say that the problem is it was one of a number of devices intended
for "low noise dual preamplifier" applications, and there wasn't really
second sourcing. It's not as if it's an standard pin-out op-amp with
some specs spruced up for a specific application. There were various
devices at the time that were about the same thing (one might argue
that they all claimed to be the best device for the purpose), but they
all had differences in pin-outs or specs.
So the NTE was a good solution, since it would be a direct replacement.
Beyond that, unless you can find a source of the LM387, it will require
some reworking of the circuit.
