err.... the OPA627 is out of the race, too heavy for my wallet and for the player.
I'm inclined between OPA2132/2228, AD823/712. I can only find AD826 and NJM4580 opamps here (it's a stupid country, i know), are they equivalent to the AD823? What are my other options as best replacements for the NJM4558?
Ok, here's what i did today, replaced the opamps for these vertical vero-boards with an 8-pin socket for changing opamps, as you can see in the picture.
It seems absurd, but no AD or OPA's can be found anywhere!
What other choices do i have?
I bought 2 NJM4580 for now, at least they are a bit better than the originals.
BTW, Guido, you're right, i have written donw one reference incorrectly, i have 1x LC7881 and 1x LC7860
