[Amps] AL-80A buzzing

I have noticed a buzzing coming from the AL-80A.  After reading a few e-mails on this reflector, I changed out the AC fan.  It is still buzzing.
  When the amp is first turned on it is quiet.  Once the amp has been on for a few minutes (without any transmitting) the buzzing begins.
  When I transmit, the buzz remains but doesn't change pitch and puts out full power.
  Any suggestions?
  Thank You
