New weekend, new hope :)

I've started comparing the board with that of my working mac 128.

(the 128)



(the plus)



I'm measuring the values inline. I have already replaced the caps on the macintosh plus board, I guess some variations in readings would be possible, but they can't be excessive?

Could anyone mark the feedback control circuit? Since the schematics in the 'classic mac repair'-document only seem to cover non-240V models...

Also, does anyone know the values of those small blue axial capacitors? (like C19,C20, C23, C26, C46)
