RCA 514 and RCA 522 IC

[oder]

Hi, and thank you for reeding this post!

I'm about to restore a old Audio Developments AD075 mixer.
Most of the channels seem to be working well except for allot of dirt and some hum so I'm going to clean it and recap as first stage.

I'm ordering capacitors and also wanted to have some spare op amp IC's. However, I am having some problems figuring out which IC's those are.

They are RCA514 and RCA522

Can anyone advice on what those Ic's would be called today so can order some from Mouser?

If this is a dumb question, please forgive me

Thank you!

try ca748ce as part # for cross reference...5534 might be pin compatible but will draw more current

CA748CE

(shabtec just beatme to it..

It does look like a standard 8 pin single opamp 741 pinout.)

Thank you for the comments!

The mixer runs on +24V only. Not +- voltage.

The opamps you mention, do they work only with positive voltage?

Thanks

YES  ...

opamps can be setup to run on +24v
