Your request suggests you only want one of them, so you are unlikely to get it post free from a legitimate dealer.

Is this the one ?

Im just doing a bit of IC rolling with the headphone amp... I want to try the Burr Brown OPA 2134 against the Analog Devices 'AD712' which should sound different.

Soic or dip? I have a load of op-amps on brown dogs from various projects, singles, doubles. Quite a few of these are obsolete now which is a shame as some of them were stellar parts. Happy to lend a selection out that suit the rails on your amp.

AD8656 dual channel 5.5v max supply
LM49870 single channel 22v max
AD8397 dual channel 22v max (310mA into 32 ohms)
LM4562 dual channel 33v max
JRC2068 dual channel 18v max
LM6643 dual channel 12v max
Ad4841-2 dual channel 12v max
LM49860 dual channel 22v max Was designed as a headphone driver
LT1678 dual 32v max
AD8656 dual channel 6v max

DIP.. Already fitted a DIP IC Base ready for da Rollin'..Im guessing it's the Analog devices that are the stellar parts :dance:

AD Litrature states the 'AD712' is an enhanced Replacement for the 'LF412' & 'TL082'

They're like most components, you'll find a fave. I can stick those two ad chips in the post if you fancy.
