On the appe 1, sometime the 22uf 25V are blue (pre-NTI) and sometime they are yellow (NTI).
On NTI boards, they can also be mixed...
But always in the same way... yellow ones for +5V and -5V and blue ones for -12V and 12V.
It seems to me that the last boards have just yellow caps...
Does someone know the difference between them?
Are the yellow ones better? Or can they support higher temperature?
