Richard, am I correct in thinking that the phono stage is the Jolida JD9? And if so, to what values have you set the input resistance, input capacitance, and gain?
In particular, if you presently have input resistance set to a high setting, especially 47K, try changing it to the minimum possible value (100 ohms). If the problem is being caused by RFI, resulting from static or anything else, that may help. If it does, you could then increase the value one step at a time to determine a setting that is optimal sonically but does not result in the popping and clicking.
Also, I'm thinking that since the noises apparently occurred with the prior phono stage only while a record was playing (per your second post in the thread), that symptom and the new symptom of noises occurring while no record is playing may have two different causes. The original symptom perhaps being static-related, and perhaps requiring either just destaticizing your records, or experimenting further with turntable grounding. And the new problem perhaps resulting from the Jolida either somehow being more sensitive to RFI, or being defective and generating the noises itself.
Are you sure that the noises you presently hear when a record is not being played sound similar to what you heard during record playback with the previous equipment?
Hope that helps. Regards,
