Please read the data sheet

Thanks...There was nothing on price and where to get it in data sheet... oh, AP and BP, yes I found about that two days ago...


Dug, thanks, I will check... Do you have any practical experience with NE5534 and those two OPA... I am thinking to replace NE5534 with OPA604 in my SONY CDP501. Would that improve sound in any way?

I used OPA604's to replace NE5534's in a Micromega with excellent results but it may not be a straight swap,

Swapping Op-Amps... you have checked to see it's stable haven't you ?

Thank you Mooly; I went to a linked thread where you explained about oscillations and op-amp stability, very good and will help me too. In regards to discussion on that other thread (Swapping op-amps...) it happens that I have an old Tekronix 465M 100MHz oscilloscope, which, at one point in the past, I was thinking to replace with 60 MHZ digital (yeah, I know, silly idea, don't know why...probably new-must-be-better thought); now I am glad I didn't.
