Hi all

I have consoles that use the 301 which is now obsolete in dip8 package (soic seem to stay alive?)
The LM301 is used in a specific way I don't remember to see elsewhere, where the input stage is bypassed and a discrete differential pair is used in place and sent to the output stage via comp/bal pin.

I'm not expert at all in opamp topology/design and like to know what other of opamp is able to be used like that.

Here the idea of discussion is not to replace for "better" opamp, I have no complain about the sound of my 169 and 289, but anticipate a possible substitution when my spare spent out or when NOS stock get completely overpriced...

LM301 DIP8, how many pieces you need? I think I still can buy it locally.

Thanks to both of you for the help.
I should have enough spare for the moment.

I'm not good enough to contribute too much but i think the Ward beck m460 and m470 preamps uses the lm301 in a similar way, bypassing some of the limitations of the internal stuff with discrete parts around it. I have dug a little bit around to find a way to upgrade the lm301 because of the bad reputation but haven't come to any conclusive info yet.  I'm very interested to know if anybody has an idea or tried something.

trim pot substitution?
