Bypassed surge protector and went directly into a single outlet, but that didn't help.

From the photo it looks like there is no earth wire from the tonearm tube to the post that the large black earth (to phono earth) is connected to.
From the tonearm you should have right channel +- ,left channel +-, plus earth. ( 5 wires all up ).
I cant see if the braid is connected - is this connected to the arm ??
If so try connecting that to the black earth wire post. Otherwise if its missing you need an earth wire from the armtube to the post the black earth wire is connected to. Look closely at the bottom of the arm - is there a loose wire/evidence of earth wire missing/earth lug with nothing on it ??
@dover Sorry, the picture doesn't show it well, but there is a black ground wire coming from the tone arm, which is soldered to the EMI screen. I did a continuity test between it and the black wire that leads out with the RCAs to the amp, and it gave me a confirming beep.
I think the problem is in the arm itself. So, I took that apart -- now I kind of wish I hadn't... but when I did so, I found the black wire was loose from the copper clip I assume is designed to ground the arm itself. I'm not 100% sure I didn't pull the wire loose from the clip in disassembling the arm, of course.
I soldered the wire back to the clip and tried to reassemble, but in the process the blue wire snapped... :(
So, now, I'm going to rewire the whole arm... argh... it will probably still buzz once I've done that... but, I'll have learned some lessons, I guess...
Rewiring the arm shouldn't be too hard.
Best way is to attach multiple draw strings ( cotton or slk thread ) to each wire and pull it through.
Then attach the new wire to each draw string and pull through one at a time.
That way you'll never end up with no wire in the arm.
Pre tin the ends of the wire before you start.
Dont use cardas - its too hard to strip the insulation properly unless you have a 800 degree soldering iron, or solder bath.
Make sure there are no sharp edges where the arm goes from the tube to the pillar.
