"Those tubes also generate considerable harmonic energy at 120 Hz."
You are right. But he WILL be able to null the 60Hz. There's not much he can do about the 120Hz harmonic. I think he already went with DC for the 845 so it's moot.
I just thought if he had a list of all the possible sources of hum it might help him track some of them down.
