Standard single (TL071) pattern did power opamp ?

[moby]

Does there exist a DIP8 single opamp (TL071/NE5534 pattern) capable of
driving a 50 ohm load while still being usable on +/- 15 volt rails
(cuts out video opamps). Trying to beef up the headphone drive of an
old Neve mixer without hacking it in any way (ie adding in current
follower transistors etc).

Depends on how many volts you need into 50ohms. Calculate the
dissipation inside the chip carefully or it'll smoke out. 50ohms is
tough. Some will do it even if not mentioned but don't push it too far
in amplitude or phssst ... BANG.

There are fast opamps that can operate on +/-15V such as the THS4021
which I recently used:

This one does video speeds with ease. But be careful, it must be
operated at gains of 10 or higher.

Certainly none that I know of. Which Neve mixer is this btw ?
