I never had hum with my FFSS.
With the usual Garrard 301?

run a 60w lightbulb in series with the motor to reduce its magnetic
field.
It reduced but not eliminated it here.
In those days, I had good hearing and I couldn't hear any.
I'd imagine your hearing is still ok for mains hum? ;-)
I can certainly hear it when it turns up on sound sysytems.
I wouldn't say it was audible in normal use but definitely there is you
whacked the wick up while not playing a record.
I remember an alleged problem when RDS first came out. Went to see someone
near Wrotham, but on the back of a hill. He turned up the volume on one of
R3 long silent pauses to demonstrate, the next minute we were blown out of
our seats by the opening chord of something.
