David: The buzz is the result of arcing between the plates of the capacitor. This typically is the result of the amplifier being too lightly loaded resulting in excessive RF voltage in the output ne
I can usually find what I need from FASTENAL. https://www.fastenal.com/ You may have to do a drill-down on their site as they carry LOTS and LOTS of screws of all types and sizes. If you need som
