About the Datassette update

Hi to everybody! Recently I have got a quite old Datassette unit (its data
cable is dated 1984) and I opened it for seeing if it was all ok.
Then, on FUNET, I found this page:
http://www.funet.fi/pub/cbm/schematics/datassette/cas-update.gif where there
are information about an update to be done on the PCB version NP-090. My
"new" datassette is NP-090B: do you know if the same update applies to this
board revision too? I checked the components and in fact a capacitor is of
the wrong value and another one is missing between two resistors.
Also, it seems that there is little difference between the NP-090 schematics
and my actual NP-090B PCB.
