You should swap your speaker cables left to right ( at speaker end only ).
If the problem stays in the right speaker - then either the speaker has issues or it is picking up rf from somewhere. Possible speaker issue could be faulty caps or bad solder joint which is more prone to rf.
If the pops go to the left then stereo more likley the problem, or one channel of the stereo is picking up rf.
Typically if you have a one channel problem, you simply swap left and right channels on one component at a time until you find the problem component.
Sources of rf - anything electrical device that has digital control of timer software running - eg fridges and air-conditioning units are a common source, wifi routers, washing machines/driers. Just try switching them off one at a time to see if it helps.
Try having all your digital gear off a separate outlet - even if you have to run a temporary extension cord. Also make sure your wifi fi routers are on a separate spur from the stereo.
Light switches and dimmers with bad contacts are another common source. I periodically turn the mains power off and go through all the power outlets and light switches in the home and clean and tighten up all the wire contacts - you’d be amazed at how bad these get over time.
It is just a process of elimination. Good luck.
