| 5534's from TI are available from Digi Key. You don't want them, trust me.
There are several subs you may get away with, depending on whether the circuit has local feedback compensation and local psu bypass caps. First try the new National LME49710, lower noise, low bias current, very low THD. The BB OPA134 is another but has a zippy top end that is irratating over long sessions. Another one if you like fast is the LT1357. Another one that's very good is the new BB OPA211 and the FET version OPA827, a better part than the BB OPA627. The 627 is a dry sounding part that's not good sounding and it's too expensive.
