That 18nF value on the schematic isn't optional, and you don't want a cap that shifts out of spec after a month in service. This Jaycar miniature metallised polyester capacitor handles it cleanly. 18nF at 100VDC, solid construction, and the kind of stability that lets you close the lid and forget about it. Priced so grabbing a few for your bench doesn't require a budget meeting
