As a few of you have done in the past, I plan to try to upgrade the LF351N op amps of my Audiovalve RKV-II by better op amps, such as the suggested OPA627.

 

I would like to know if I can simply replace the LF351N by the OPA627, or if there is some particulars points to check , based on your experience.

 

For those who have done this modification, can you explain the improvement ?

 

Thanks for your replies,
