That filter stage needs a touch more capacitance, or your coupling cap has cracked and you need a drop-in replacement that doesn't care which way it faces. The Jaycar 47nF ceramic is exactly that: fixed-value, non-polarized, 50VDC rated. Ceramic dielectric with metal electrode layers gives you stable behaviour across the frequency range you actually care about. No polarity to check before you solder. Pack of two means you've got the spare in your tray while the first one's cooling down on the board
