[sdiy] LM13700 substitute

[Harry Bissell Jr]

I found that the NJM part does not have as wide a
range
of input common mode voltage.  Both meet the spec, but
the National part is considerably higher in practice.

Good designs do not exceed this limit (5V) anyway.
It took me a long time to find out why the National
parts worked and the NJM did not.

RTFM   :^P
