Turns out Mouser still have some leaded TL072 (NJR NJM072BD, order
code 513-NJM072BD). It is given as equivalent to a no-suffix
TL072.

I've compared the data sheets and haven't found any obvious
discrepancies. Some of the "typical" figures differ (E.G. the CMRR
and SVRR : 100 dB at TI, 86 dB at ST and 76 dB at NJR) but how
much of that is real and how much is different definitions of
"typical" ?

The NJR data sheet is much less detailed than the other two. It
avoids mentioning crosstalk completely, for instance.

Does anyone have any experience with those NJR chips ?
