In Reply to: RH84 test amp: driver stage wiring change = lower THD% posted by deathtube 667 on September 15, 2016 at 16:46:39:
I was monitoring the AC line to see if changes to the mains voltage (120VAC) would cause changes to THD% at the output of my amp.
There was a dryer running on the same 50A subpanel as my amp.
Sure enough, if the AC line would sag a bit (about 2.5V) the THD% would increase by as much as .07 - .1% @ 1.2W power output.
The noise performance seemed to suffer a bit while the dryer was running as well.
