Unfortunately, I don't have a probe. I did listen for sound but all I remember hearing was the low hum usually associated with these sets. I will try again when it's dead quiet to see if I notice anything. Only thing that's bothering me is all the other times I ran this set, there was no focus pulsing. Could it be something caused from removing the chassis last time , transport of the board from a to b, and when I put it back in?
