Power supply info on the GGG LM3886 amp?

[petemoore]

  Yes...I know...
  I didn't see an actual application sheet diagram for an actual LM3886TF amp.
  This one is humming real loud like AC's getting right in there.
  I used 1n4003 diodes, but they don't seem to hold up.
  I have V- > -2200uf+ /Gnd./ -2200uf+ V+, these capacitors are on the amp board, tied to the +/- of the diode bridge.
  It'd be neat to see exactly what 'is' done as far as power supply diagrams w/stated components, and basic layout information.
  I have a computer PS box I cleaned out, the mains in goes in/out through a 1'' corner of the box to the transformer primary, the secondary lines come in the other end of the box to feed the diode bridge board, the amp circuit board [with the two filter caps] is on the other side of the box.
  I was wondering if having the caps separated from the diodes via wire makes voltage surges across those wires or something, I have those caps very near the amp.

  Works fine I guess with the filter caps right next to the amp [a couple 2200uf w/.1's on 'em].
  I had the input wire like dangling and touching ground, probably picking up some sewage...
