That 2.7pF on your schematic isn't a 2.2 and it's not a 3.3. You need the exact value, and you need it now. These Jaycar ceramic capacitors are fixed at 2.7pF, rated to 50VDC, and non-polarized so you don't have to double-check orientation under the magnifier. Two in the pack. Solder one, keep one. Sorted
