I have a Geffel M582 tube SDC that belongs to a client. It very intermittently produces a popping/ticking sound, like an idling two-stroke engine. Audio still passes when the noise starts up. I haven't been able to get it to happen on the bench, but my client provided an audio clip of the sound. I thought I would ask around the community before I dive in to this rabbit hole, as it doesn't seem to happen often.

possible capsule related issue.

I would try a different tube and rule that out

Do you have another capsule to screw on and try? That sounds like the diaphragm could be sucking against the backplate if it’s worn out or has pinholes. Perhaps a close look at the diaphragm under magnification is in order.
