content: You need to be a bit more forthcoming on what the use is. There is no exact equivalent but many that can do the same job or better but it depends on the circuit it is being used in. Is it a general audio buffer or preamp or...... what?

content: Thanks for that CJay, Maplin is a long drive, with me being out in the sticks, so I have ordered from RS and will let the postal service do their bit. Appreciate the tip though!

content: Chances are the TL071 once was DIP only - when it was new, there was not much SMD.

content: I'm fairly sure it was. I don't recall when SMT ICs started showing up but I have some boards that are over 35 years old that have DIP package TL071's and TL082's on them. Those are fairly ubiquitous parts that have been around for a very long time.
