I have a 416T that is clunking intermittently (usually after a few minutes clean). Any thoughts on what this could be? A failing cap? It does seem to happen specifically when connected to my Sony camera, so I suspect the 48v phantom power supply to be not that great, but I haven't had this issue with any modern P48 powered mics.

It's the original "without crystal" model and I've tried both the PSC barrel and the circuit design from Uneeda audio to do the T power conversion. The clicking started out as a very occasoional thing but has become more and more persistent. There is usually a big click, followed by random small clicks at random intervals.

Any help would be much appreciated.
