[R-390] Humming Transformer

[Drew P.]

I have a '67 EAC whose power transformer mechanically hummed
to the point of distraction.  My solution was to loosen the
6 captive screws which hold the transformer/power supply unit
to the mainframe, each about 3 turns.  Then, between the
surface of the hanging transformer and the table top upon
which the radio sits, I shoved an old glove for padding such
that the weight of the transformer rests on the "padding"
and the table top.  This made the transformer nearly silent.
