You need 16.000MHz for the CS9233 and 16.9344MHz + 24.576MHz for the CS4248. The small capacitors can all be 10µF and sound will come out fine (original likely had a number of 1µF ones but that is only gonna limit low freq response). The two larger ones near outputs should be as high value you can physicall fit since that determines the low freq response, 220µF and higher is the ballpark there.

Thanks!!!

any ideia of top crystal X1 near DSP-9410A ?

there are some close-ups here: https://retrosoundcards.wordpress.com/categor … allant-sc-8000/
X1 is 16mhz xtal

It is probably 12, 16, or 24MHz, like seen on Creative cards and many other clones.

EDIT: it is definitely a 12MHz ceramic resonator that is supposed to go there.

there is a high res pic here: https://allegro.pl/oferta/isa-crystal-cs4231a … oxz-17487770525
but I have found no easy way to save it ... it does show that X2 is 12mhz though

my bad, X2 near DSP

Some view source and save

Thanks for the tip!

I think i have all information to try revive this card 😁
thank you guys!
