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

[editted:] 958B = M51958B - voltage detecting reset logic ?
