I don't believe there has been any revision to the PCB for the KNB1
in more than eleven years, and only one revision to the Errata sheet.

Even though the KNB1 manual mentions a revision D PCB, that has never
been issued.  The manual also states that on the revision C PCB, the
model number is mis-written as KBN1 instead of KNB1, so that's a way
to verify rev. C.

It's pretty safe to say your PCB is a revision C PCB.  Don't forget
to add the capacitor shown in the errata...it's pretty important.
