trying to identify this IC in Schlumberger tme 5310

[manulaudic]

Hi,

I have this Broken ic in my cards. It doesnt deliver proper voltages. I can't seem to remove the heatsink to read what ic it is so i thought i'd ask if anyone worked on this channel strip before.

Thanks it's a long shot i know

I didn't worked on it, but think this IC is LM325.

Hello

As moamps said, look like a dual regulator.

Probably you can remove it and short 4-2 and 5-7, feeding +/- 15v to the module.
A clean +/-15 will do the job if it's a racking project without the need for the extra regulation

If you need to feed +/-18, you can probably replace it with LM78(9)15.

Wonderful !

Makes sense, i have a regulated power supply i could indeed feed it + and - 15v ! Wonderfull i'll try that

Thank you so much for your help @moamps and @zamproject

Thanks guys ! that did the trick. removed the IC and already has the connections for 15v from schematic so there was no need to wire pins together.

Cheers

Hi, not relevant to the IC issue (that seems to be solved anyway) but very curious about the TME 5310, how is it?
