HP82143A Repair - Buzzing While Powered On

[cesarb94]

Hi Tony, forgot to mention, In the mean time I've rebuilt a battery pack with SC cells. So this buzzing happens with either batteries, AA and SC.

I've also tried to poke every component to see if the sound changes pitch, but no luck.

Best regards.
