[QUOTE="Family_Dog, post: 705236, member: 82"] The capacitor acts as a spark suppressor for when the switch operates, thus preventing arcing of the switch during on and particularly off operations. It cannot cause the transformer to hum or vibrate. What you can do is to check that the mounting screws of the transformer are tight and it would be prudent to check the solder connections as well from the transformer leads to wherever they go to in the circuit. The 3900 is only a 22w per channel amp so there are no dangerously heavy currents there. Check that the fuse (1.5A) is not possibly arcing in the fuse holder. Does the Sansui work perfectly otherwise, i.e. no distortion or buzzing on any of the channels when switched to, say, auxiliary input? -F_D [/QUOTE]
