Static electricity: Unique to Vinyl Systems?

I have recently replaced a turntable/cartridge and a phono preamp, but on both systems, I get a lot of pooping and clicking noises that occur even when a record is not playing. This does not happen with the digital sources in the same system.
Is this some kind of static electricity that only effects analog? Would something like a zerostat fix this?

Good to hear.

So was it external RFI or some internal issue or issues with the phono pre-amps I wonder?

Good to hear. RFI is only increasing. I ended up shielding my AC power from my dwellings service entry to the audio systems power cables. An under 1K upgrade that provided a substantial improvement.

RFI generally does not make clicking sounds. It really sounded like it was a preamp problem, and you seem to have confirmed that. I think you had bad luck with two preamps that both had problems. RFI is often accompanied by hum and buzzing sounds that come and go....

Definitely it's not RFI, but static charges that haven't been filtered or choked. Poor caps or weak caps, poor circuit engineering is the cause.
I get them once in a while becouse I need to recap my full function preamp.

I'm a happy camper now because I plan to spend the next several months listening to as much vinyl as possible.
I fail to see how I solved a static problem with a new preamp.
