ciao a tutti,
I'm about to restore a card reader from an HP65,
does anyone know what the capacity of the capacitors is ?
Thanks for help, Alberto

I measured them on a unit I restored as I thought they might be bad.
From left to right on your picture:
20.9 micro farad
20.9 " "
15.9 " "
Don't know what the design values are, but the card reader works.
