TL072 on IC110 on 1.01a board

Ok, so hopefully this is my last question in this forum ;)

It's specified in the build tutorial:
" IC110 (TL074) has been replaced by IC1 (TL072) "

I can't find IC1 anywhere on my board, so I suspect that means that IC110 is to be replaced by TL072. What I can't figure out is, how should it fit in this socket? TL074 is a 2x8 IC and TL072 is 2x4, so it's half the size and I am not sure how it is supposed to be put in.

Like this?

Hope my question makes sense - I am quite sure the confusion is because I have 1.01a board where it's not always all clear what is supposed to be done.

I am planning to compile everything I have learned in my process of building the Nava and putting it here for new people who have a 1.01a board where some stuff is not all clear.

When did you order the bom? I think you may have a later one related to V1.02. Check the "Nava BOM" post and its updates pinned at the top of the Hardware forum.

Right, I do have a TL074 from the BOM that I ordered..

Hmm, ok, but well TL074 work in conjunction with the MUX_SH board? A bit confusing.. Maybe I should just try it out and see what happens ;)

If your board are other than v1.02 you should use a TL074.
Do not solder C517, C518 and C519.
