LM13600

[Jim Patchell]

    Yep, the LM13600 is no longer being manufactured by National
Semiconductor (those bastards).  It depends a lot on the circuit as to
weather you can substitute in the LM13700 (they both have the same pinout,
but the LM13700 has the darlington follower unbiased, where in the LM13600,
the darlington is biased by the Iabc current.
