My Icom R-71a has two small ceramic disc capacitors shunted to ground on each of the two antenna connectors. These capacitors don't appear on any of my schematics. Does anyone know the purpose or actual ratings for these capacitors? They are very small, size of a pea, and have 33 on them. I am assuming this must be 33 pf. owing to their small size. I am replacing the electrolytic capacitors and broke the lead on one of these small capacitors. Any help would be appreciated. Wayne Hicks Austin, Tx.
