Buzzing through speaker's tweeters - PrimaLuna Dialogue Two Integrated

Hi Everyone,
I have a PrimaLuna Dialogue Two integrated amp that had all its tubes replaced in Jan. 2019.  Last night I noticed buzzing through my speaker's tweeters when using the Aux 1 input (from Audible Illusions phonostage).  I had not started playing any records and the buzzing increased when I moved up the volume knob.  It would decrease when lowering the volume.  I swapped to the CD input and turned on the SACD player, dead silent.  I swapped my AI phono to a solid state phonostage, but nothing changed.  Still got the buzzing at about the same intensity.  I even moved the RCAs to Aux 2 and still the buzzing.

I emailed PrimaLuna but hope that maybe someone on the forum may know what is causing this and how to fix?
Thanks!

Same problem, my problem seems to be a bad turntable cable, catching rfi.
 
Very annoying also that I'm near radio broadcast towers, sometimes that's in there too, sporadically.
