[sdiy] DIP LM13700 discontinuation

[Richie Burnett]

I was just about to post the same thing!  I was amazed to see that this is 
still the case after seeing those exact chips used in mixers 30 years ago!

Bearing in mind the rate of change in the electronics industry, it's
worth acknowledging that this has been the case for 30 YEARS or more! I
was working on broadcast mixers back in the early '90s and the opamp
lineup was exactly the same. Those devices just tick most if not all the
boxes for a wide range of audio applications, and the multiple sources
and ubiquity they have built up helps prolong the situation.

Yes, there are modern alternatives but the improvements are usually
marginal and often offset by cost or single-sourcing. The NE5532 shows
its age a bit with its power consumption and tendency to go unstable
without some decoupling caps nearby to keep it company and I admit I
tend to use the MC33178 in that position now, but the TL07x is still a
go-to device.
