How can I correct this problem?


In the old tube-type radio days, 60-cycle hum could be mitigated by simply
turning the plug 180� in the socket. Today, it's tougher, what with
polorized plugs and sockets.


Hi,
60Hz hum and hash noise are two different animals. Reversing plug
reversed polarity of the transformer winding minimizing inductive
coupling. Poorly made cheap power supplies have no noise supression or
shielding. For an example, compare mil-spec. vs. commercial grade vs.
consumer grade power supplies.
