Just a thought.
I know people mention that the filament supplies are noisy for the preamps of vibrochamps. So here is my question.
If you pull all the preamp tubes from a VC and you still hear the hum can, at least temporarily, rule out that the hum is from the filament design and focus on things like the power supply?
