I have ordered the two 1000uF, 200V input caps and should replace them
in about 3 days and will let you all know the results.
The input filter capacitors serve no RF function, so won't solve anything

He ought to very carefully check the AC supply connection from his PSU to ground - any resistance there due to tarnished pins would send EMI way up.
BTW:
a portable AM-SW radio can be used to "sniff" for the source of the EMI.
