hi thanks for the reply but this schematic is really way of.
ín this psu are the following chips present, none of them are present in the CX70-CX75 schematic:

primairy (hot) site:
TNY277P       -  AC/DC offline switcher
LM2903         -  low power dual voltage comparator
UCC2818AD -  Bicmos power preregulator
M51995AFP  - switching regulator control  

secundairy(cold) site:
958B             -  voltage detecting reset logic ?
UC2573D     -  Buck pwm  step down voltage regulator

so maybe better alternatives are for sure welcome
