Default Re: Some really great news

In that case your statement is confusing me.

Quote "The grounding is specific to the switched pcb, in not switched mode, with the SUT and one input. So would not apply to other configurations. Is anyone getting hum?"

Can you explain so that non technical bods can understand please ?

What you seem to be saying is "one input", "non switched mode" and "SUT" ?

That is what I'm saying. Without the SUT the grounding isn't critical.

My phono 3 is the non-switchable, single input type with SUTs.

Just turned the system up to max and no hum, just valve hiss.

Does this help or confuse things?!

No not a realistic volume level but to be far I canít say if theirs hiss at volume levels that the whole street can hear but thereís a lot to be said about adding good parts a more smoothing cap

No not a realistic volume level Mmmm, I think we can all say that. Not sure how smoothing caps help hiss though?
