Finally working again on my revised extra-large-diaphragm crystal microphone design (based off the cortado circuit, of course), and I’m having noise issues. Does this sound like damaged-transistor “wind” noise to you?

(I can’t find anything else wrong, all the solder joints look good, it’s just noisy as hell and idk why.)
