Look at that capacitor carefully under good light and magnification.
See if that "330" isn't really "33G". If so, it is the 47pF that you seek.

That is a voltage rail that you are checking, and you should measure
somewhere close to 250 or 300 ohms. I assume you do not have the
Control Board plugged in yet - if you do remove it and remeasure.

The resistance between U6 pin 8 and ground was 295 ohms in my K2 built in
