I just replaced a switching power supply in my Robotron with the original linear power supply. when I turn on the machine now, there is a 1-2 second "HUMM" from the speaker, which then subsides to a "buzz". all game sounds are normal, but the background buzz bothers me.
This seems to be a new issue -- any ideas?
