Philco 84 now has a hum

It is strange, the asynchronous motors are not known to be big offenders.
You could try to buy/build a large enough filter and plug through it.
You could start with a few microfarads of capacitance in parallel to the lines. I doubt Y-caps would do much, the noise is likely the differential one.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
