Restoring a card reader from an HP65

[Alberto Fenini]

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.
